Based on Fermi’s Paradox (where are all the space aliens, if they exist?). From RT:
A Russian theoretical physicist has predicted a grim future for our civilization that “is even worse than extinction.”
Alexander Berezin, a highly-cited scientist from Russia’s National University of Electronic Technology Research, outlined his bleak prediction in an article entitled ‘First to enter, last to leave: a solution to Fermi’s paradox’.
He thinks that the aliens will try to eradicate all competition, including us, to fuel their own expansion and be the power in the universe.
While that dog-eat-dog theory may seem harsh, Berezin says total destruction of other life forms likely won’t be a conscious obliteration. “They simply [will] not realize, in the same way that a construction team demolishes an anthill to build a property because it has no incentives to protect it,” writes Berezin.

Maybe that’s what he means by the worst part. Not being an enemy jut a nuisance.
Here’s a thought: If theorists cannot contemplate the possibility that the reason we are not hearing from Them is that They are just not out there, they invent crazy theories.
If the term “denialism” weren’t already taken, it would certainly come in handy here.
