A lot of you are still talking about this as though it's about handing free money out to people who choose not to work.
The current discussions around UBI in the wake of increasing developments in AI technology are pertaining to the possibility that there simply won't be enough work. That's it. Not giving people more free time to pursue their interests, etc, but supporting the population that simply doesn't have work because the work isn't there any more.
We've become dependant on working to make money to buy what we need, as opposed to working to grow our food and build our own shelters, etc. We don't work to survive, we work to earn, to enable us to buy to survive.
There won't 'always be work' whilst we still pursue the desire to have machines do more and more for us. There WAS always work when to have hot water we had to build a fire and boil it ourselves. To have food, we had to grow it, pick it or hunt it. To have clothes we had to make them.
A variation of this theme has been present since early man. It's only really been relatively recently that the majority of us have not had to do so much for ourselves. If we went back just 50 years, we'd find ourselves having to do more 'by hand' as it were.
The only real way out of this is to go back to doing for ourselves, not for the 'middle man' of earning enough to pay someone or increasingly something enough to do it for us.
It's like we have all have servants now, just not human ones. Jeez, we don't even have to turn a light switch on now if we don't want, we just ask Alexa.
