Yeah, probably. Still hope it will be an option in the future. I think the biggest jump in popularity gonna heppen when there is gonna be more developed apps for browsing it, considering that some QoL problems could be fixed by those developers.
No, i mean not all, but local from other instances. I dont remember why i needed it, probably discussion of more specialised instances out there. Most down to earth example i can imagine now would probably be trying to find instance on your local language (other than english, ofc).
Tbh if google suffers catastrophic failure my passwords probably gonna be pretty far in the list i need to worry about lol.
Whole idea is weird and as of now its lacking features. Like no ability to look on the other instance local feed without registrating there (at least not in apps i use). Also needing to type whole adress with instance name if you want some community from other instance is unhandy.
Also, as far as i understand, there can be the same communities on different instances, so you could subscribe to, idk, cat community on lemmy.ml, but not see anything from cat community on lemmy.world. If its true its kinda stupid, i think there should be a way to associate comunities across fedarated instances.
Hell, even registration is kinda messed up. As lemmy.world shown, you easilly can sign up on overpopulated instances which would drop several times a day. Not sure, it probably fixed for now, but that was a problem when i started.
So far i like the idea and want it to succeed and become popular. But with how elitist people here are usually towards users from other platforms and with overall roughness it kinda seems unlikelly. Maybe it will change when current apps get better, or reddit app developers make versions for lemmy, idk.
It wont help a ton of businises, banks, and government stuff relying on google in varying capacity to work lol.
