I thought this was slightly funny.
Mark Zuckerberg is known these days for wearing t-shirts with Latin phrases on them, especially ones where he compares himself to Julius Caesar.
Bluesky made a shirt in the same style, but theirs says “a world without Caesars” in Latin.
That’s because its new. ActivityPub has been around for 7 years now, and I’d argue its totally stagnated on Mastodon to the point that the fediverse is mastodon to most people, and the norms of message passing are ruled by mastodon. Whereas atproto has been around for 2 years, one of which was in a very small and restricted alpha stage to get the core blocks stable. Now we see so many projects getting off the ground, some of the ones I mentioned being the most mature. With that said they are all earlydays, as is the protocol.
If we really want to talk about massive leaps, and a vibrant dev community thats actively build and expanding the protocol even faster than atproto, than its Nostr. Problem with them is the community building it 😅
