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?

I'm building a decentralized Airbnb competitor. We're currently in the process of buying a building to use as a test bed. I've been told this is depin, or at least there are VCs that look at it that way.
