Understanding the brain alone will take a hell of a long time.
ya. but he's saying it's impossible
Also jobs like doctors cant be replaced entirely by robots. The surgeons hand and muscle memory is far superior to what any robot could ever do. Besides, I don't think anybody will trust his life to a robot anytime soon. Robots will simply make jobs easier, not replace human workers.
once you make a robot that will adapt to a specific person's insides, it would easily beat anything a human surgeon could do
speaking of which, I don't get the obsession with "hand-made" stuff, like car parts or something. for something like a human body, where the robot
would have to change its behavior, that will probably take a while to come around
but with car parts and stuff? they're always the same. machines don't need to adapt. they have specific instructions, and will perform flawlessly, unlike a person. it doesn't make sense to me why you would value that over a machine's work
