> The AI researchers I know often say they expect the AI to replace their own jobs.
Are they expecting the equity they get in some AI company will save them personally from economic ruin, so they're fine with that outcome for everyone else?
Or are they expecting AI technology will magically make our society communist?
I know people who believe the end state is a Star Trek-style post-scarcity world.
This is not the same thing as communism. You can still have private ownership, differing levels of wealth, entrepreneurship, and competition. It's just that having money is not necessary for survival or to lead a reasonably comfortable life.
And they don't believe it will magically happen -- it will take intentional action by governments to get there. This is, perhaps, the reason the AI labs are talking so much about AI replacing people's jobs. It's not arrogance, it's to make sure our leaders are thinking about this now instead of when it's too late to guide the outcome.
The former.

Yes. Basically based on my conversations with coworkers who went to these frontier AI labs: this is happening anyway, so they may as well make the money while they still can.
