Pretty much the title sums it up. There’s a lot to be concerned about, and one thing I find personally disconcerting is how US educational systems might be impacted.
Do we need to make backups of, like, everything educational and scientific? And where are all the places and forms that we can host these materials?
Edit: to everyone saying it shouldn’t be an issue because Trump/US doesn’t control information in the rest of the world, keep in mind that is little comfort to those of us here if access to that information becomes restricted as well. We should be seeking to hedge all bets.
Not all literature is privately owned. I don’t think you’re quite aware of how many research studies, trials, and such are funded by the US Government. All of that information is currently accessible to quite a few people. What happens when it no longer is? And that’s just one example.
Of course the federal government has a great deal of influence over current and future research, but that isn’t the topic. OP’s asking about existing literature.
