I have to disagree about AI and doctors, until at least you can get much better sensing technologies. Computers are only as good as the data you feed them, and someone saying they have a pain in some vague region really isn't enough to diagnose anything accurately. It's why doctors tell people to not use the internet to self-diagnose: they quickly determine they're dying of some rare syndrome when really they just have heartburn. A human doctor can interact with human patients (most of whom are not very logically-minded) and figure this stuff out; a computer can't. Remember, a lot of diagnosing depends on the symptoms a patient self-reports, which is bound to be extremely error-prone. Now, if we get to the point where we have Star Trek-style medical scanners, then things will of course be different, but that's a long ways off. However, I totally agree about the labor-based economy crumbing well before unemployment reaches 50%. If 30% of the workforce is displaced by automation, our economy won't work any more the way it's set up now. It's why we really need a Basic Income.
