I think we can all agree that "use humans for raw energy" is a really stupid idea, and sounds exactly like someone dumbed stuff down. FFS, a small Rickover fission reactor the size of a van (1950s tech) produces the same amount of heat as, what, 200 000 human bodies? (And why humans, with all the complex support systems? Why not a heap of compost, if one insists on bio-source?)
Whereas using our brains for compute (in the background, or during REM sleep) makes perfect sense; power efficiency is excellent.
nono...it's "combined with a form of fusion", you see, so it's obviously based in science.
People obviously know this stuff is absurd on some level, but it doesn't stop them from cherry-picking the parts they "like" (i.e. fear) and ignoring the rest.
