Idk if reddit will actually "die"
I think it depends on us users. If we can make a community work here in the federated space well enough to draw users then reddit might really go away.
But if they manage to kill off 3rd party devs, APIs and etc quickly before these alternatives are baked enough to work for their users and these existing federated tools aren't good enough -- then they'll just maintain via the network effect.
The screen on my X just cracked and we’re hoping it holds together long enough to get the new usb-c model. Since we plan on keeping it that long again I’d like to get everything to the same cable.
