What are the "DePIN" projects that people think are most likely to actually work?

It feels like the category is a new name for something that's been around for a decade (StorJ, various decentralized ubers...) but has never gotten off the ground? So what's the bull case for why it will get off the ground now?

When I am performing a sewing project, e.g. making a t-shirt, DePIN should be removed a stitch or two before the needle is to DePIN. This allows the presser foot to be on top of DePIN but not move the fabric out of position. DePIN is there in the first place to keep the layers from sliding. 

Make sense???
