This is a little melodramatic, no?
Access to information, even without Wikipedia or Reddit, can still be found easily (compared to pre internet days) I personally don’t use google search anymore, but can still find links to public MIT textbooks (like SICP or Deep Learning) by searching on there. I’m sure google scholar, scihub, and arxiv will be around for a good while.
I’m sure if Wikipedia falls, another encyclopedia would take its place, since so many primary sources are still discoverable if you know the terms to search for. Maybe with a paywall, maybe not.
