But I really hope Musk himself is not framing things this way: that humans will have to merge with machines because they'll be useless otherwise. I can't separate the inflammatory headline and text from what Musk himself said, though...
I guess it's not too out of character given Musk's apparent treatment of his own employees, though.
Merging with machines and other similar things should happen because it benefits humans, not because it's necessary to make someone money or because someone decided that humans are "useless".
