I mean, Solana does 3k tps on a good day (with less electricity than a google search and a fraction of a penny fee). So it’s not un-believable there will be a decentralized ledger that hits visa levels of throughput in the next few years.

I agree though that a centralized solution would be more performant, but it would have to have network effects for it to gain widespread use, which means it would be a monopoly and enshitify and start taking an unreasonable fee. So government should step in and offer something for online micro transactions, but at government speed we might be decades out.

So then we are back to decentralized ledgers…. Not technically better but organizationally, politically, socially better…
