I don't think the $15k price tag is intended for regular consumers. I didn't listen to the Lex Fridman interview (my patience starts to wane after the first two hours), but I did listen to another of Hotz's interview on another podcast, and I believe he referred to this their "Tiny Box" as more of a dev box. It's for the engineers and tinkerers who want a capable machine for AI. So while expensive, it fills a niche for those who don't want to deal with linking multiple Nvidia GPUs together and deal with the power and cooling setup that come with that.
