> Why would you want massive amounts more of those things? In fact I might even argue that medicine, taxation and education are a net negative on society already. And that to the extent that there seems to be scarcity, it's mainly a distribution problem having to do with entrenched interests and bureaucracy.

I'm not sure what you mean. In my country getting a specialist to take a look at you can take weeks, the scarcity is that there's not enough doctors. For sure many people get delayed and suboptimal diagnosis (even if you finally get to see the specialist, he may have 10 mintues for you and 50 other patients to see that day). A.I can simply solve this.

>> That's is the actual scarcity tho

Not necessarily, the labor costs a tremendous amount, and also it might be that we don't need to cram tens of millions of people around cities anymore if most work is automated, we can start spreading out (again, this will take decades and I'm not denying we have pressing problems in the immediate future).
