I think the likelihood that UBI will “destroy humanity” is actually pretty low! :) But you’re entitled to your opinion!
And contrary to what you claim, there are many millions of instances of people being lifted out of poverty by long-term financial assistance programs.
But if you think you have a better alternative to a UBI, please set it out in detail in an article of your own. If you think we should have a job guarantee program, please say, in detail, how that would work. I look forward to seeing your proposals.
