Regarding a super intelligence creating new cures: a million plus people die from malaria and AIDS combined each year. We have effective treatments for both, yet the USAID was recently shut down. I enjoy technology but less and less so each year, because it increasingly feels like there’s some kind of disconnect with the real world that’s hard to put my finger on
A follow up would be to observe that in many places today, inequality causes substantial sub-populations to feel that they are not thriving, or even declining though GDP is increasing. Which would explain the rage of the middle-American and many Europeans.
If you buy all this, then there is a clear path by which radical abundance resolves the problems. Same as how the Baby Boomers were a very low-polarization generation; when everybody is thriving it’s a lot easier to get along.
Personally I worry more about the possible worlds where technology doesn’t bring us radical abundance. Declining empires with nuclear weapons don’t sound conducive to a fun time.
