If you look at lightning ⚡ as a self custodial payment network, it is great. But that's only a snapshot of the present situation.

If you consider that it must become 99% custodial once Bitcoin adoption rises significantly but Bitcoin core stays the same, it becomes a "slightly better than traditional banks" payment system.

Could still be a plus for society. But we shouldn't praise lightning as "the future of money". The improvement just isn't big enough.
