I guess it’s a good thing that I don’t know a couple of the “Bad tech” ideas. I can figure out the metaverse land sales but have no idea what a blind box is.

The only blind boxes I know are those little toy collections you purchase in an opaque wrapper or box. You don’t know which one you got until you’ve paid. Generally some kind of licensed product, so movie/TV characters, or whatever else will get a child to talk their parents into spending money. There are others aimed at adults, too, like mini versions of classic branded products (Kitchenaid stand mixer, Kraft mac and cheese box, etc)
