But as others say, at the end of the day if everyone has an extra $1000 a month, there will be groups such as landlords trying to jack up prices.
To counter other commenters on this issue - we do have price controls on things such as milk, bread etc and it does 'work' to some degree. In the landlords example above - a smart gov would implement an algorithm for 'greed' and fine/tax offenders and put that money into the UBI cash reserves.
I think UBI as a real possibility needs to be taken seriously. The level of AI has accelerated in such a short timeframe that (imo) we're starting to see the knock on effects into society. This is just in tech for now - thousands applicants for positions, and no one really needing to hire juniors as Claude et al easily replace the tasks they do.
Once other industries realize that they can replace a lot of tasks with ai, we'll see a gradual shortage of jobs for unskilled admin jobs (not manual labour... Yet)
There's a lot of shouting about AGI but the current LLM landscape effects are slowly happening around us right now. UBI studies should be taken more seriously and at a larger scale.
