IRC and email isn’t dead and they are completely anonymous. Web ain’t gonna die. TCP and UDP ain’t ever gonna die. HTTP ain’t ever gonna die. HTML ain’t ever gonna die. JSON isn’t even part of the web but it de facto is now. At this rate JS ain’t ever gonna die unfortunately. The web is safe. The internet is safe. Everything is open and it can’t be taken away or killed.

Think of it like climate change. The internet is going to be just fine. Its whoever is trying to benefit from digital IDs that will go extinct on it, and the internet will have healed itself from them.
