Elon Musk sees technology as taking over the human world and we’d best consider our options. Ma points out that humans build computers but no computer has ever built a human: For Musk, technology is not a tool to promote humanity. Rather, technology will take humanity’s place of leadership in the world. Humans will have a choice to integrate with our technological masters or be left behind as a relic of evolutionary history, just one more living fossil roaming the landscape. It is interesting how the theory of evolution contributes to this idea of a technological singularity (an endpoint of human history as we know it). Ma, while impressed with technology, is more impressed with humans. He points out that Read More ›

Apparently, design is okay if microbes do it: It seems so obvious that someone should have thought of it decades ago: Since parasites have plagued eukaryotic life for millions of years, their prevalence likely affected evolution. Psychologist Marco Del Giudice of the University of New Mexico is not the first researcher to suggest that the evolution of the human brain could have been influenced by parasites that manipulate host behavior. But tired of waiting for neurologists to pick up the ball and run with it, he has published a paper in the Quarterly Review of Biology that suggests four categories of adaptive host countermeasures against brain-manipulating parasites and the likely evolutionary responses of the parasites themselves. The idea has implications Read More ›

Eric Holloway takes on a reader’s question: Reader: Harris basically reduces everything to atomic physics and says all causality happens there, so the world is deterministic (i.e. no free will). While I vehemently disagree with that idea, I do respect that at least he can articulate himself well. Do you have any thoughts on the matter? Eric Holloway: A deterministic physical world does not imply that free will doesn’t exist. Look at it as an argument in four steps: Free will is not deterministic. The physical world is deterministic. ? Free will does not exist. Harris needs to fill in missing step 3 to arrive at his conclusion. One possible premise is that the physical world is all that exists. Read More ›
