You have to define what you mean by "useful"?

Monero's fungibility is excellent, but the transactions-per-second ain't that great right? Also Proof of stake is inherently more sustainable in a resource-constrained world: you don't want to replace banks by something more wasteful thank banks...

For my money's worth, and clearly talking my own book here, the decidedly zero-hype Algorand is the useful crypto at 20k TPS, this is the Visa/Mastercard territory where things get interesting. As for fungibility, it will have to be some democratically controlled thing I think...

You're right about how "useful" needs to be defined. Monero at 30tps and blockchain growth rate is useless for global adoption. Lack of fungibility also makes every other cryptocurrency useless for global adoption.

You're also right that PoS is more sustainable than PoW, but I think this will change your mind: https://old.reddit.com/r/Monero/comments/lv5285/alt_take_on_... It did for me. Thankfully since the energy consumption does not scale with the transaction rate, it's not a long term problem I think. Currently, the high energy per transaction stats are only because the adoption is low.
