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?

What the Arweave team has done with AO is more than impressive. They've managed to combine DePin in both the traditional and blockchain worlds. To the largest and most reliable hard drive, they've added a super scalable computer.
