If you are interested in AT Protocol and AP and how it may impact Fediverse, then you should take a look at this thread from one of the main authors of AP: https://octodon.social/@cwebber/110295117475083222. Actually you should study the papers referenced there.

the Octodon
@activitypubblueskybridge Upshot:
1. Nomadic identity and portable contents are eminently doable in AP
2. Don't get into AT vs ATP war. There is not much that one can do that the other can't.
3. Don't get into personality war. People working in both the camps are well qualified.
4. Keep the eyes on the prize - Decentralization bc it benefits the users.

These all see like very wise statements to me.
