Do you know how long it took before ActivityPub became relevant? 10 years.

Nostr will scale better than ActivityPub in multiple different ways, I assure you it is a better foundation. But it requires one person to build a perfect library in each programming language - which nobody has done yet in JavaScript. Didn't it take you 2 months to build that in Go? This is a lot of work for one person. But I will do it.
