Yang is probably my favorite Democratic primary candidate. I think his $1000/month UBI proposal is unworkable and doesn't survive sober scrutiny[1], but I'm glad he's around making the case for it in a mainstream setting. UBI deserves some mainstream sunlight. We already have UBI in the form of SS/Medicare (which are going bankrupt, but that's another discussion); UBI is a natural extension of that. I believe after enough economic growth and technological progress, UBI will become possible, maybe even necessary.
