There's been a social experiment going on here at the moment (Australia) - everyone has had UBI for a while in the form of unemployment for everyone who needs it, and paid at a rate that you can live on.
They're finding it hard to get people to pick fruit and so on - it used to be done by back packers who aren't coming because travel isn't happening. Strangely, no one thinks to pay people more to pick fruit and stop it from being a shitty job, instead they lowered the amount they're paying for unemployment. UBI effectively creates a new minimum wage, there are still a lot of jobs no one wants to do, so techtopia will have to wait a while imho.
I mean really one answer here is: maybe we as a civilization don't actually need mass-farmed fruit, because it's not actually cost-effective to produce and consumers clearly don't actually value it very highly.
The point of UBI is a grand solution to stop us having goods and products which depend on creating a defacto underclass.
Crypto was such a shit show.
