I do see it happening naturally; the very idea that an UBI idea is floating around is a product of the wealth and automation we enjoy. It's a realization that sets in on a broad front, from bullshit jobs, to new generations of products that are not improving much or even regressing, environmental concerns that discourage producing more, massive government budgets squandered ("why not give it to the people who need it?"), and COVID giving people a pause in their respective hamster wheels.
Imagine a technological reset and/or war: Under those circumstances one could still argue for a socialist system of work, but not for people doing nothing getting UBI.
