population projections they already predict that prosperity reduces population and even if AI becomes good enough to replace most humans the economic surplus does not disappear it's a coordination problem in many places on Earth social safety nets are pretty robust, and if AI helps to reduce cost of providing basic services then it won't be a problem to expand those safety nets ... there's already a pretty serious an…
I think the concerns with UBI are (1) it takes away the leverage of a labor force to organize and strike for better benefits or economic conditions, and (2) following the block grant model, can be a trojan horse "benefit" that sets the stage for effectively deleting systems of welfare support that have been historically resilient due to institutional support and being strongly identified with specific constituencies.…
... also, one pretty practical problem with UBI is that cost of living varies wildly. And if it depends on location then people would register in a high-CoL place and live in a low-CoL place. (Which is what remote work already should be doing, but many companies are resistant to change.)
In theory it makes sense to have easy to administer targeted interventions, because then there's a lot of data (and "touch points" - ie. interaction with the people who actually get some benefit), so it's possible to do proper cost-benefit analyses.
Of course this doesn't work because allocation is over-overpoliticized, people want all kinds of means-testing and other hoops for people to jump through. (Like the classic prove you still have a disability and people with Type I diabetes few years have to get a fucking paper.)
So when it comes to any kind of safety net it should be as automatic as possible, but at least as targeted as negative income tax. UBI might fit depending on one's definition.
