I don't have enough expertise in this field but I don't think we should be thinking only with a doomsday scenario, humans are quite resilient and innovative, society will completely change and I genuinely believe we will find ways, there will be a lot of suffering in between (and maybe after as well, as there is now) but we might eventually reach a point in automation where a lot of prices drop to the point where it's virtually free, food could be included, if we do have 24/7 machines that can build, expand, deliver and so-on with free energy somehow, it's not crazy to think that a KG of chicken could worth 10 times less than it is now, so many things could be reconsidered.

UBI could mean also that people could be living in places further away from main cities, and eventually housing will be automatically built as well so costs could drop sharply.

Of course humans will adapt, the core issue is how we can avoid as much suffering as possible while these changes happen, that's always the point. No one wants to live a life during a transitional period in history where suffering is increased, as a species we should be working to alleviate that.

What's the point of progress if we keep repeating the same mistakes of leaving miserable people behind? Is that progress or just a repetition of the cycle with new shiny things?

> but we might eventually reach a point in automation where a lot of prices drop to the point where it's virtually free, food could be included,

It took two world wars till we had an aberrational period where the middle class actually had lives which were good.

UBI can’t happen because governments globally don't have the money to pay for it. Its good to hope, but the details aren’t in favor.
