Eric Holloway: The Salem hypothesis as to why engineers doubt Darwin

Spread the love

Not because they’re terrorists or black-and-white thinkers, as claimed. A simple computer program shows the limits of creating information by chance:

Engineers are more likely to be creationists because they are familiar with what it takes to design complex things for specific tasks. Which is exactly what we see in the biological world. Additionally, engineers who work with computers know about randomized methods, which include evolutionary algorithms. We are aware of their significant limitations…

Let’s set my evolutionary algorithm a simple, fundamental task — to count by ones…

Exponential is bad news. Exponential means it took the evolutionary algorithm twice as long to count to 10 as it did to count to 9.

Let’s put exponential on a cosmological scale. The heat death of the universe is projected to occur in 10106 years. This is well beyond the lifetime of anyone who’ll even remotely know we existed. Seems like a lot of time, but not for exponential doubling!

If we generously say that a step of P’‘ runs in a nanosecond, which is nine decimal places to the right of the dot, then the universe will undergo heat death before the evolutionary algorithm can evolve a program that counts from 0 to 500. And it takes even longer if the program must start from 1 instead of 0. To go up to 501 doubles even that. Completely impossible.

Eric Holloway, “The Salem Hypothesis: Why engineers view the universe as designed” at Mind Matters News (June 7, 2022)

Takehome: Engineers doubt chance evolution because a computer using an evolution-based program to do simple tasks would be chugging away well past the heat death of our universe, as Eric Holloway demonstrates.

Note: The hypothesis was named in honor of Talk.origins contributor Bill Salem.

    i am a mechanical engineer with a decent IT background, so it would be weird, if i won’t comment on this …

    I as an engineer, I have no doubt that life on Earth was created. I would stake my life on it. I know what i see and i can only laugh in any biologist’s face … The only question is, how it was done.

    Biologists can claim what they want … they are dead wrong … they are so wrong, they even don’t realize how wrong they are … because they never made anything … they don’t know what they are talking about … the problem with biologists is, that their unqualified claims mislead lay people …

    The Salem “logic” is typical pop psych, like Dunning-Kruger or “bullies are insecure”. I’m tired of that crap. Life doesn’t work that way.

    Engineers are designISTs because engineers are designERs. We know the power and the limits of design. We know that a bug-free product is impossible, so we recognize that the self-debugging process of life can’t be 100% perfect. Even so, we also recognize that it’s infinitely beyond anything we can design.

    The closest we can come to self-debugging is a mechanism that improves with wear, like the sleeve-valve engine. But it’s still not self-repairing or self-checking like every cell in the world.

    obviously, it is close to perfect. Some species have been around for hundreds of millions of years. Can you imagine anything man-made working for 100 years without any outside intervention /maintenance/repair ?
    I could, if i was a fairy tail writer or a Darwinist (which is basically the same)

    PS: the fact that such species still exist, is the ultimate proof of design.

    Yes, close to perfect. The real secret is that a mechanism with analog negative feedback doesn’t have to be close to perfect. A well-designed loop can factor out some imperfections, and life has an infinite number of loops guarding loops.

    Let me quote from a debate on Quora.com

    Keyword: Checksum
    Someone asked a question about how reliable is the windows file copy process.

    Someone replied:

    No you cannot trust any copy process at all, if I/O gets interrupted e.g. network outage while copying from local to network, the target file will reside there and have the full filesize while the content of the file is filled with only zeros. Even if the writing process does a checksum of the bytes that were sent to the File Handle, there could still be some low-level program/driver (like antivirus) that fools the application and reports that the bytes have been written while in reality they did not arrive on the filesystem or they have been crippled in some way on their way from the application through all the layers down to the physical disk.

    If you need to make sure that something was copied guaranteed, there is only one chance to do that: after the copy finished, you have to read the target file and make a checksum of the contents, compare them with source.

    Dawkins’ weasel program is a failure in the grand scheme.

    Seversky says:

    Engineering is a fine profession but engineers are not scientists. Engineers use – but did not invent – algebra or geometry. Neither Newtonian mechanics nor Maxwell’s equations were discovered by engineers. The strange realities of relativity or quantum theories were not revealed by engineers.

    Engineers build on and from what is already known. Where lives depend on them getting it right, they cannot afford to do anything else. Science, on the other hand, is about exploring the unknown with all the uncertainty that entails.

    Biologists generally accept the theory of evolution, in spite of its imperfections and shortcomings as the best account we have at this time of how life has diversified and flourished on Earth. A significant number of engineers attack the theory with a vehemence that suggests that they fear it somehow poses a threat to their most fundamental religious beliefs. If they were truly as scientific in their approach as they claim then they would be asking themselves why this should be. What possible threat can the theory of evolution pose to engineering?

    Go to any lab. Every single thing in that lab is the product of an engineer.

    You heard about Large hadron collider ? There are lots of scientists working there. But who built the collider ? Scientists or engineers ?

    Are you saying, that engineers don’t know anything and have to ask scientists how to design things ?
    Are you saying, that without scientists there won’t be engineers ? Or what are you trying to say ?

    I said it before, but let me repeat it:

    In 21st century!, this theory claims, that sophisticated fully autonomous self-navigating flying systems somehow self-designed, with no help from engineers.

    The theory is as stupid as it gets …

    PS: let me remind you what Alon Musk said in 2021 about self-driving cars (self-driving cars much easier than flying systems, because flying systems have to move in 3 dimensions.)

    The article starts:

    Tesla boss Elon Musk has finally admitted what many automotive industry experts have long realised: autonomous vehicle technology is a lot more difficult than it seems, due to the countless variables a car must learn, detect, and avoid while on the move.

    Alon Musk:

    Generalized self-driving is a hard problem, as it requires solving a large part of real-world AI. Didn’t expect it to be so hard, but the difficulty is obvious in retrospect.

    Further evidence that seversky is clueless: Approaching Biology from a Different Angle:

    Systems biology is a loosely defined term, but the main idea is that biology is an information science, with genes a sort of digital code. Moreover, while much of molecular biology has involved studying a single gene or protein in depth, systems biology looks at the bigger picture, how all the genes and proteins interact. Ultimately the goal is to develop computer models that can predict the behavior of cells or organisms, much as Boeing can simulate how a plane will fly before it is built.

    But such a task requires biologists to team up with computer scientists, engineers, physicists and mathematicians.

    My program shows evolution is not weak, it just doesn’t work. If you think evolution does, add your idea to the program and see if it solves the exponential blow up. This is a great way to make ideas about evolution concrete.

    On the other hand, it is trivial for a programmer to avoid the exponential blow up. This is because the programmer understands the code, whereas no matter what evolution operator you add, the operator never understands the code. That’s the fundamental difference between a mind based explanation for the origin of species versus a evolution explanation.

    Silver Asiatic says:

    EricMH

    Could you explain in a bit more detail what the program is doing and why it is exponential?
    The goal is to count numbers.
    So, you start with 0 or 1 and there are 8 possible numbers. So, evolution randomly mutates the first number until it gets the second. Then it mutates 8 numbers again until it gets the third.
    Why is that exponential? Let’s say it takes 10 min to get the first number. The second would be 10 and also the 3rd.
    Why isn’t that 30 minutes and not 1 million minutes?

    Querius at 27,

    A strange article. The wording is off. The goal is the best solution, the best piece of hardware, not ‘thanks to the cloud and some software and we get all these choices.’ No, they don’t. In order to save time and money, and weight, the best answer is always the best answer. No one chooses other answers in engineering or anything else. Weird.

  29. 29
    Querius says:

    Generative design basically takes a set of specifications, constraints, or parameters to generate a set of possible solutions. There are often multiple solutions left after AI filtering. This is because there’s often no “best” answer, but rather there are answers based on different trade-offs.

    https://www.generativedesign.org/01-introduction

    Applications are typically for mechanical design, although I’m aware of the technology being used for city planning, construction, and other disciplines, including architecture.

    In this example, you can see the trade-offs between several solutions:

    https://www.generativedesign.org/01-introduction/01-02_generative-design

    Often results can look very “organic” since biological structures such as bones often optimize on light weight. Manufacturing of these shapes would be impossible without additive manufacturing (aka 3D printing). Comparing some of this technology to bones, one can appreciate the dynamic responses of biological systems, for example, bones grow and thicken internal spicules along stress lines.

    I’d suggest that the intelligence is programmed into the software, which is then applied to the problem with successive iterations. Intelligence is embedded in the process rather than in individual specific solutions.

    But my original question in 27 is an honest one.

    What BS. I could come up with any number of engineers who were more creative and radical than most scientists. Example: Claude Shannon almost singlehandedly (coming after Hartley and Norbert Weiner started the work) established information theory, with an MSEE and BS in math. He eventually earned a PhD in math but as a masters project single handedly demonstrated Boolean algebra as the future basis of computational hardware, and so established ‘switching theory’ (an archaic term) in the most important masters thesis of the past 200 years.. Example #2: R.E. Kalman, EE originator of the Kalman filter, a tour de force of applied mathematics absolutely unforeseen by mathematicians. It was so radical that he decided to bypass all of the IEEE section journals and possible resistance there and published the first related paper in a mechanical engineering journal. http://www.cs.unc.edu/~welch/kalman/

    EricMH says:

    @SA the evolutionary algorithm is not evolving the number sequence itself. It is evolving a program that generates the number sequence.

    If I modify the program to keep the previous solution population, so it’s not starting from scratch each time, the exponential time increase is still there. This gets to your scenario. Here’s the data from the modified experiment.

    256.0
    1773.0
    21625.0
    18121.0
    30959.0

    2318573.0
    2920256.0
    11101407.0

    The reason why it gets exponentially more difficult is because the programs get bigger, and with bigger programs there are more ways to get things wrong. Additionally, more junk is accumulated as evolution progresses, which makes the problem even more difficult.

    A correct solution looks like this:

    .+.+.+.+.+.+.

    The ‘+’ increments a counter, and the ‘.’ outputs the counter value. So the above program generates the following sequence: 0, 1, 2, 3, 4, 5, 6, 7

    To evolve to the 8 sequence, the evolutionary algorithm just needs to insert another ‘+.’ in the appropriate position.

    On the other hand, look at the best solution the evolutionary algorithm found for the 7 sequence:

    .<+<.+.+.+[.+[[.+<.+[+-.+-[

    Most of those characters are junk. They are valid commands, but contribute nothing to the solution, or are fixing mistake commands.

    Software has no intelligence. It can be given instructions to sort things given certain parameters but it has no intelligence, meaning human-like intelligence. Before this technology, what did human engineers do? Nothing? And this “knowledge” did not come from machines but human beings. Engineers don’t have time to sort through 200 or more “answers.” Again, prior to this, human engineers worked it out on their own. This is an assistive technology, not a replacement for human thought.

    Software can indeed employ “artificial intelligence” to respond to inputs/stimuli. The “intelligence” includes the capacity to “learn,” which means it’s programmed to create or modify rules of response and then evaluate the outcomes.

    For example, how familiar are you with a Chess program called Alpha Zero?
    https://www.chessjournal.com/alphazero/

    Alpha Zero taught itself chess in about four hours of playing against itself and now has the highest Elo rating in the world. Here’s a link to a preprint technical paper on the subject:
    https://kstatic.googleusercontent.com/files/2f51b2a749a284c2e2dfa13911da965f4855092a179469aedd15fbe4efe8f8cbf9c515ef83ac03a6515fa990e6f85fd827dcd477845e806f23a17845072dc7bd

    Yes, engineers often don’t have time to “do it right,” but they always have time to “do it over.” Very few designs spring into existence fully formed and complete, but are usually the result of many iterative improvements. Be assured that I’m not suggesting that generative design can replace engineers, but I agree that engineers can use generative design as a tool, especially if the generated designs are filtered down to perhaps six or fewer.

    Querious at 39,

    Software can’t learn anything. Not like people do. Take chess. Put in all possible moves and responses, develop a feedback loop and it just has the answer in memory. Yes, programs exist that can do trial and error and correct errors, but if it’s not programmed in, it can’t do anything.

    I suggest you walk into a room filled with engineers and say “… engineers often don’t have time to “do it right,” That’s just nonsense. Engineers sent men to the moon in the late 1960s.

    Engineers have no time to deal with [fake word] designs. You don’t seem to understand that. Decades of work has led to aircraft like the SR-71. A lot of testing went into that before actual prototypes flew.

    And another thing. I am tired of the Global Cabal of Relabelers and Repackagers whose only job is to come up with fake words and fake terms to give people the illusion we’re living in “the future.”

    One more thing. There’s no such thing as “Additive” manufacturing. Fake and more fake. So instead of making a mold and pouring hot metal and then machining it (grinding down any imperfections), parts can be constructed in a device that avoids some steps. Engineers still have to figure it all out before it goes through that process.

    I’ve seen designers design things and they have to know about materials, stresses and other things. The head designer can then pick the best handful of candidates. The engineers can then select the best way to manufacture whatever it is and choose the best, most suitable materials. But 200 or more? No. Not ever. Not in civilian applications.

It is a grotesque … moreover, that part (that swingarm) can be only manufactured using a metal 3D printing … i am pretty sure, that the metal 3D-printing of that swingarm will cost more than the whole motorcycle… From what i could understand, and i personally can see why, that swingarm can be manufactured ONLY using metal 3D printing … you can’t use molds, or any other mass production technology – because of swingarm’s ‘alien’ shape …

    This is it – in real life, this software feature has a very very very limited use (basically, it is useless) … But good for Autodesk to have such a software feature … they even claim that “it is going to revolutionize manufacturing over the next decade.”… LOL

    However, in all these cases, the downside is the inefficiency. Algorithms have to check thousands, millions or billions of solutions to reach the level of humans checking just a few solutions. So, such techniques only work when the problem domain has been constrained enough for brute force search.

    Information is the reduction in options, and constraining the problem domain to be searchable is a matter of reducing the number of options. That is the role of the human engineers. We create the information that makes these algorithms effective by reducing the search space to a manageable size. There is no way to replace the information produced by engineers using an algorithm.

    The future of AI technology is going to be this hybrid between humans constraining the problem domain, and the algorithms brute force searching for solutions within the constraints. Humans do smart things slowly, and computers do stupid things quickly. The idea will be to figure out what are the smart slow things to hand off to humans, and the stupid fast things to hand off to algorithms.

    For example, to get rid of the exponential explosion, the evolutionary algorithm can be constrained to only add the “.” and “+” characters to the end of the solutions. This constraint, of course, requires intelligence, since the constrainer has to understand the program pattern of ‘”.+.+.+.” and how it generates the count sequence.

    Regarding the scientific method, software developers exercise the scientific method every single day many times to debug their programs. Bugs often are non obvious, and we have to form hypotheses and falsify or confirm these hypotheses. We also have to infer logical laws and causes to find the root cause for the bug. Additionally, we often use the scientific statistical toolbag in this debugging. Software engineers are lucky, since we can step through our programs to see the behavior in real time. Other engineering disciplines have to be even more rigorous and insightful in their use of the scientific method, since bridges and rockets don’t have debuggers you can attach to the finished product 🙂 So, I would say engineers use the scientific method much more frequently than scientists, and are much more aware of how the scientific method works. Finally, our use of the scientific method has to actually work. Scientists just need to get their peers and grant committee to accept their claims, the claims don’t actually have to work in the real world.

    ET @47,
    You’re right in specifying a qualification. It’s Darwinian evolution in tiny increments by random mutations filtered by natural selection that doesn’t seem to work.

    Martin_r @41,
    The largest users of additive manufacturing are in medical and aeronautical industries. According to an online course I once took in the subject from Deloitte University, there are several technologies commonly employed. One example, used in the class showed how supply chains are changing in some cases. One of the examples they provided involved the U.S. military. To service the rotor of a type of helicopter, a special tool is required. Rather than fill up the supply channel with these tools, they issue 3D printers in the field, where additional tools are printed on demand.

    AI is indeed used to generate 3D honeycomb patterns in parts for the purpose of reducing weight while maintaining strength. The employment of finite element modeling (aka FEM/FEA) to determine stresses has been used for many decades in mechanical engineering. An architect neighbor of mine fed it my deck cover design to make sure it could support a heavy man walking across it. These data can show exactly where something needs to be beefed up. 3D FEM was used in the 1980s to optimize stratified ignition in the shape of automotive cylinders.

    I’d agree with you that engineers use technologies as they do any other tool, whether its a 3D printed prototype or CAD/CAM/CAE software.

    EricMH @43,
    What the Alpha Zero AI does is not simply a “brute force attack” against a chess position, and it doesn’t trim branches of unpromising lines as do typical chess programs, but rather it develops rules and priorities by trial and error. These types of rules enable AI routines to “recognize” general types of shapes in a photograph such as kitten or a boat.

    I completely agree with you regarding the use of the scientific method for debugging software or finding design flaws or limitations.

    Out of curiosity, have you ever tried simulating an ecosystem using software? I’d suggest that stable ecosystems are also evidence for design. Optimization for the survival of only one specific organism is likely to “crash” an ecosystem, causing a devastating loss in carrying capacity. It seems that any ecosystem must be harmonized to sustain life (for example, think of what the introduction of rabbits did in Australia or what kudzu did in the southern USA).

    As Michael Behe said:

    Again, as I made abundantly clear at trial, it isn’t “evolution” but Darwinism — random mutation and natural selection — that ID challenges. Darwinism makes the large, crucial claim that random processes and natural selection can account for the functional complexity of life. Thus the “burden of proof” for Darwinism necessarily is to support its special claim — not simply to show that common descent looks to be true. How can a demand for Darwinism to convincingly support its express claim be “unreasonable”?

  52. 52
    EricMH says:

    ET @ 47
    The reason I say “evolution” instead of “Darwinism” or “random processes” is that all evolutionary mechanisms are random processes + natural selection. Nothing outside of that is taken seriously, e.g. saltationism, lamarkianism, and so on. Plus, Dawkins makes a pretty good mathematical argument in The Blind Watchmaker why nothing besides random incrementalism can work for evolution. So there is no real distinction.

    These are all the genetic mechanisms I’ve run across:
    1. random insertions, deletions, and mutations of nucleotides
    2. gene duplication
    3. meiosis
    4. horizontal gene transfer

    On top of that is only natural selection, where fit offspring reproduce, and unfit offspring are eliminated.

    The second part of evolution is the relationship between genotype and phenotype. Dawkins type weasel examples neglect this difference, but my algorithm faithfully reproduces this aspect of evolution. Genetic mechanisms operate on the genotype (the program code in my algorithm), and natural selection operates on the phenotype (the program output in my algorithm).

    So Fred @ 46, this is the reason my algorithm is representative of the power of evolution. My algorithm includes all of the above. I’ve not run across any other aspects of evolution that will significantly change the algorithm operation. If you know of any, please mention them. Otherwise, we can consider my algorithm to work or fail insofar as evolution works or fails. In fact, this was the original motivation behind evolutionary algorithms, the mathematical issues brought up during the Wistar Symposium in 1967. John Holland, the inventor of the genetic algorithm, specifically cites the Wistar Symposium as the reason for his interest in genetic algorithms. Where participants like Murray Eden and Schutzenberger saw mathematical difficulties and impossibilities in evolutionary theory, John Holland saw evidence of evolution’s spectacular power. Holland then invented the “schema theorem” to explain how evolution could be so effective.

    Many decades of research into evolutionary algorithms hence, we’ve seen Holland’s anticipation completely squashed (and the schema theorem disproven). There is nothing special about evolutionary algorithms that can explain how biological evolution can overcome the difficulties brought up during the Wistar Symposium. In fact, they tend to be bottom of the pile in terms of tools engineers reach for to solve problems. My algorithm is a good example of this failure. So, at this point, evolutionary theory has been put to the test in real time in the make or break world of commercial software, and has found very wanting. There is no reason to subsequently believe that some magic makes evolutionary theory work in biology.

    On the other hand, as my example also very clearly indicates, the Wistar Symposium mathematical problems are easily eliminated when a mind is involved in the solution creation process. So, the obvious implication is that a mind is involved in the biological creation process as well.

    Finally, if any evolution theory die hards think I missed some magical operator that makes evolution work, all you have to do is add it to my code, or tell me here in chat to add it, and we can see if it’s the missing piece to this puzzle. No need to have decades of drawn out speculative debates online. We can test evolutionary theory easily on the computer and come to a conclusive answer.

  53. 53
    ET says:

    Taken seriously? Is that your argument? There isn’t anything about Intelligent Design that is anti-evolution. Intelligent Design is OK with organisms being designed with the information and ability to evolve and adapt:

    He [the Designer] indeed seems to have “carefully crafted” information in His species giving them the ability to respond to environmental stimuli to alter their own genome to adapt to new environments. He then evidently let them wander where they will with the ability to adapt.- Dr. Lee Spetner “the Evolution Revolution” p 108

    And in “Not By Chance”, Spetner responds to “the Blind Watchmaker” thesis. For example, duplications, followed by building it a binding site, and then changing the duplicate for some new function, isn’t justifiable as a blind watchmaker mechanism. Transposons carry within their sequence the coding for two of the enzymes required for the gene to move around.
    .
    On top of that there is artificial selection. And we see what that can do in a relatively short time.

    The link between genotype and phenotype is with the traits. Traits such as eye color and shape. Detached or attached earlobes. Cleft chin. Dimples. In his book (English title) “Why is a Fly not a Horse?”, the prominent Italian geneticist Giuseppe Sermonti, tells us the following: Chapter VI “Why is a Fly not a horse?” (same as the book’s title):

    ”The scientist enjoys a privilege denied the theologian. To any question, even one central to his theories, he may reply “I’m sorry but I do not know.” This is the only honest answer to the question posed by the title of this chapter. We are fully aware of what makes a flower red rather than white, what it is that prevents a dwarf from growing taller, or what goes wrong in a paraplegic or a thalassemic. But the mystery of species eludes us, and we have made no progress beyond what we already have long known, namely, that a kitty is born because its mother was a she-cat that mated with a tom, and that a fly emerges as a fly larva from a fly egg.”

    I doubt your algorithm does as you say as no one knows what determines biological form. We know it isn’t DNA. DNA controls and influences development but that only means it determines whether or not development doesn’t have any issues.

    you seem to be familiar with terms like 3D printing, FEM, CAD, CAM, and so on. That is why i have asked you what is your education. You sound like an engineer.

    However, i have to insist on what i wrote before, this GENERATIVE-DESIGN technology has a very very very limited application. Basically, you confirmed it. It very reminds me of so called evolutionary/genetic algorithms (EA/GA). These also have a very very very limited application. I think, this AI GENERATIVE-DESIGN technology is another fancy [fake] word for EA/GA (like Relatd pointed out)
    But again, EA/GA is nothing new too. It just another fancy word for optimization algorithm.
    Of course, i can’t entirely judge from one Autodesk PR article, but from what i could understand, i am pretty sure it is still about the same (EA,GA, GENERATIVE-DESIGN, optimization algorithm).

    Please don’t get me wrong, i am not against any additional engineering tool, i am just saying, all these technologies have very very limited use in real life engineering (unlike FEM, CAD, CAM etc.) that is why i called it “another AI hype”. Because lay people (e.g. Seversky) may think, that you take a computer with a proper AI software, you put in some variables and it will design a cheetah-robot for you.

    Let me add to yours … in my debates with Darwinists, EA/GA were mentioned very often. Darwinian debaters claimed that “look, even engineers use evo/genetic algorithms. People here at UD know that i am a mechanical engineer. I never heard of EA/GA, i never used EA/GA. I heard of optimization algorithms. You may say, that i never heard of EA/GA or never used them (as an engineer) because i am backwards. Few years ago, i made my own survey. I got in touch with some international robotic companies dealing with humanoid robots design (including Boston Dynamics). I have asked a very simple question “if their engineers use EA/GA when designing robots”. I have received some answers … I won’t name the companies, i don’t have the permission, it was a private communication.

    Anyway, here is what they replied:

    A company from Spain:

    Our engineers do not use GA/EA in our company and due to that, I can not help you with much more. Wishing you all the best.

    A company from Italy – in this case i talked to 2 engineers, both of them are also academics (university professors)

    Engineer #1: “Quick answers: I was engineer for 20+ years, No, we haven’t used genetic/evolutionary algorithms.”

    Engineer #2: “From my personal experience I agree with you in that I don’t see a lot of activity around this topics in the robotics industry.”

    A company from France:

    “No we haven’t used such technique in real cases. It seems a great tool allowing the exploration of different design/approach. Yet, I have only seen such uses in research applications atm.”

    PS: Boston Dynamics did not reply, and i urged it a few times. No reply. The funny thing is, they even have a robot named “DARWIN”

    Martin_r,

    My educational background is scientific, but my vocational background is primarily in industry. I’ve had the privilege of interacting with many engineers in many different disciplines worldwide. Plus, I read a lot.

    Yes, the biological world screams design to engineers who recognize the mind-boggling technologies and capabilities of biological systems. They realize that shooting bullets randomly at a Tesla will never result in design innovations. Bullets can only destroy things. But if you’re in a Tesla being swept down a river in a flood and can’t get the window open to exit, bullets may open a window, destroying it save your life.

    Engineers understand the importance of knowing the specifications and constraints of any project. They are intimately and sometimes painfully familiar with their experiences dealing with trade-offs and compromises.

    Specifications include performance, time, cost, reliability, manufacturability (including common parts, and tolerance costs and stacking), testability, manufacturing yield, flexibility under changing conditions (temperature, humidity, pressure, dust, mud, corrosion), robustness, repairability, upgradability, usability, compatibility, and “charm.” I’m sure I missed other factors. This is one reason why designs improve by successive approximation after being subjected to random use and abuse.

    An important point is that hyper-optimization and over-specialization makes an organism, an ecosystem, a business, an entire economy, or an individual career fragile and subject to extinction. Even academics realize this as they learn more and more about less and less until they know everything about nothing. (grin)

    Examples in biology include ecological and agricultural monocultures, and also the risks associated with a lack of genetic diversity in specific organisms. Introducing cats, rats, wild hogs, and a host of other invasive species can devastate an ecosystem, which leads to my observation that the survival of an ecosystem may be at odds with the success of any component species.

    AI, machine learning, and generative design are programmed to develop and apply rules to an environment along with instant feedback. Also, parametric technologies embed a specified range of variation into a design. The intelligence is already programmed/designed in to generate different configurations, but they mimic the behavior of intelligence when their behaviors are actually an extension of intelligence.

    My best example of AI is in well-programmed chatbots (or trollbots) that mimic human communication and pass the Turing test. Here at UD, there are a number of contributors that might indeed actually be trollbots, judging from their pattern of abusive comments, lack of new information, and vacuous responses.

    One more note regarding the antenna…. no EA/GA will tell you, then you need an antenna to receive a signal… first you have to invent the antenna (including materials the antenna is made of). Then, eventually, you can optimize the shape of that antenna.

    Moreover, as far as i know, this antenna was designed for NASA spacecraft. That means, it is a single piece(s). No mass production. It is very possible, when there would be a need to manufacture such an antenna in large amounts, engineers would revert to more simple antenna design to lower the production costs, and ignore EA/GA results (and still have a pretty good antenna)

    and one more thing regarding the materials (e.g. the NASA antenna is made of)

    The cell is an engineering marvel… no doubts … but what amazes me, is how the cell creates all the needful hi-tech materials at body temperature (e.g. bones, ceramic teeth)… no blast furnace is needed… no material suppliers are needed … the cell creates everything, a complete product … this is an engineering SCI-FI … look at 3D-printers … if you want to print something, you need to add a filament …

    Another firm that I’m familiar with designed high-voltage electrical insulators for transmission lines. I’m sure most people know what I’m talking about.

    There are several materials available for the core, which come only in certain diameters, there are several available disks or cups that can be made from insulating materials, the lengths are in increments of the disks or cups, and there are also several styles of end connectors available.

    Each combination and its dimensions have different electrical properties. What this company did was create a program that accepted a customer’s specifications and their routine provided approximations closest to their specifications that they could choose from, along with their prices.

    This is an example of “artificial intelligence” from the 1980s. It’s called AI because you can’t tell whether the output was generated by a human engineer or a program.

    The antenna’s design is one that works. No one will redesign it if it needs to be mass produced.

    Most 3-D printers that people can afford are junk. The stated resolution is low. The build area is small. The imperfections in the form of visible layers preclude making quality consumer products. Good 3-D printers cost thousands and are way beyond the budgets of most people. Even well-financed companies have to use these sparingly since all costs to operate it need to be factored in.

    Martin_r @93,

    I share your admiration for the astounding complexity within a cell and the instructions used for it to grow and maintain its interior structures. The cell certainly uses additive rather than subtractive technologies (such as cutting, milling, and turning) and doesn’t require melting anything at high temperatures.

    As to additive manufacturing, you might be interested in exploring some of these technologies, including photopolymerization:

    The materials being used have also progressed significantly although the “grain” and orientation (based on its shape) certainly need to be taken into consideration. I’ve been particularly impressed by carbon-fiber impregnated materials and the ability to blend from one material into another.

    Querius,

    additive manufacturing vs. 3D-printing, what is difference ?
    I can’t see any at the first sight.

    I personally consider the cell as a very advanced 3D-printer. And i am not the only one. A time ago, i watched a TED talk, and to my surprise, this guy Riccardo Sabatini (obviously a Darwinian scientist) thinks the same:

    For the next 16 minutes, I’m going to take you on a journey that is probably the biggest dream of humanity: to understand the code of life.

    So for me, everything started many, many years ago when I met the first 3D printer. The concept was fascinating. A 3D printer needs three elements: a bit of information, some raw material, some energy, and it can produce any object that was not there before.

    I was doing physics, I was coming back home and I realized that I actually always knew a 3D printer. And everyone does. It was my mom.

    My mom takes three elements: a bit of information, which is between my father and my mom in this case, raw elements and energy in the same media, that is food, and after several months, produces me. And I was not existent before.

    I can’t see any at the first sight.

    AM is supposed to be a generic term covering a variety of technologies to contrast with material subtraction. 3D printing is one such AM technology, but the terms are now often used interchangeably. There are seven processes recognized by ISO:

    Here’s a fun example of the use of powder bed technology for an inconel exhaust manifold.

    Inconel is an extremely tough alloy when compared with stainless steel.

    The cell is essentially a biosynthesis lab and fabrication center that’s fantastically more complex than anything humanity has ever created. And information is central to the processes within the cell.

    Querius,

    thank you for clarification.
    I see there is a lot of progress in this field. Nice stuff.

    Now, when you look at this high advanced human made technology, it still looks like a child play. Seriously, the theory of evolution occurs to me like a hoax, or a conspiracy. How can an mentally healthy educated 21st century person think, that the cell with all what it can, is a product of some blind unguided process ? The cell is an engineering marvel … i seriously doubt, that it ever will be reverse-engineered.

    You’re most welcome. I’ve had many conversations with engineers on the subject who use AM for their work or projects. Applications go well beyond engineering. For example . . .

    – An art director in the film industry once described how they laser scan an actor’s head and then 3D print it, so that makeup artists can try various experiments without requiring the actor to sit for them hours at a time.

    – In the scientific press, one can read about 3D printing a liver using live cells, and calcium phosphate to print bones (the tiny perforations in the result promotes bone attachment to the prosthesis). I’m sure this is still experimental, but I know it’s been done with metal prosthetics.

    In the course, I once took in the subject, I was amazed to learn that the crossover between AM and traditional injection molds was much higher than I’d ever imagined: about 100,000 units!

    Now, when you look at this high advanced human made technology, it still looks like a child play.

    Yes, exactly! The more we learn about cells, the more complex and out-of-reach the biotechnology appears, which always the opposite of what’s expected. Consider that biologists once named the undifferentiated substance that filled cells “protoplasm.”
