What would a post-apocalyptic internet look like?
Obviously there's more than one kind of apocalypse that could affect the internet in different ways, such as a nuclear war or a virus that leaves physical infrastructure intact.
So for the first kind of internet, after the nuclear war, let's assume that its only a handful of data centers or small servers connected to a other devices via a small handful of satellites and fiber optic cables that remained intact or were restored after the nuclear war? Basically just a lawless internet with limited browsing and slow speeds, but no one can stop you from creating your own website or whatever.
The second scenario one is pretty much exactly as we have it now, but there's less online presence, considering most people are dead, let's say somewhere in between 60-75%. So then influencing no longer has enough users to be profitable because they're busy with other roles. And because corporations aren't making money anymore, there's no ad slop, only local ads created by other users who are still alive and want to buy or sell stuff.
Let's assume that a few nuclear power plants are still operational and delivering all the necessary power. How would this online society behave?
Didn’t think I had to say this, but please ignore how nuclear power plants are operational. It could be hydroelectric or whatever, but something is generating continuous electricity and is irrelevant to this.
