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?

the original DePIN concept is probably a decentralized RPC server network (what we're building)

now, depin is likely one of the most promising ways for retail to get involved in crypto this cycle (if not onchain social). Projects like Helium etc leading the way
