I can’t currently log into lemmy.world, and browse peer-tube, yet if I leave my instance, I’m no longer in my account. So you say to just create a peer-tube account. Ok, but now that’s fragmented. There’s two accounts. And then maybe I want to share pictures. Well now I need a pixelfed account. Ok, now that’s 3 accounts for 1 fediverse. And the list only grows. Mastodon? 4 accounts.
I see a future where you log into 1 account from your instance. From that home page on your instance, you can interact with any service that hasn’t banned you, or defederated from your instance. ANY fediverse service. With one account. You can write mastodon messages, post a video to peertube, check your email, post some pictures, whatever. And all your notifications will be in one place. Organized. A centralized decentralization if you will.
I just see a world that doesn’t exist, and I want it to hurry up already

Hey, I think maybe you misunderstood me. The “all under one account” thing is possible for the most part - here’s the PR which allows mbin (and thus mbin accounts) to do peertube https://github.com/MbinOrg/mbin/pull/782 and in pyfedi (and thus piefed accounts) there seems to also be peertube integration https://codeberg.org/rimu/pyfedi/src/branch/main/app/community/util.py#L75 along with pixelfed integration ( https://codeberg.org/rimu/pyfedi/src/branch/main/app/user/routes.py#L981 ) - though I’d grant that you’re correct about there still being rough edges that need to be cleaned up, but I am confident that they will get cleaned up over time.

So that part of the vision is pretty much already here. The only thing is if you want to create and own the magazine/community (the 3%) … well see https://github.com/MbinOrg/mbin/issues/869 (but I think even remote account ownership is on a wishlist somewhere, so even that may get taken up some day.

There’s even an open item about being able to transfer your account to another instance (account portability), see https://github.com/MbinOrg/mbin/issues/171
