That’s entirely dependent on the interface switching, or some kind of universal interface. That’s the part I have serous doubts about. Keep in mind you have to make a single interface that work better than all the others on their respective native systems. I’m not sure that’s possible.
That sounds good.
I’m not saying that they shouldn’t be able to interoperate at all. Just that this kind of thing isn’t, and never will be ideal. I’m pushing back on the idea, that one account for all the Fediverse is the best and greatest, that everyone should be striving for that goal.
It’s a principal of reality. Trying to make something that can do everything, will mean it’s not great at anything. Specialization is what allows society to grow to what it is. The Fediverse is no different.
