I realize this question walks the line of fitting the subreddit rules in that it must be "A question about the human past". So, 20 years ago people were using the internet. 12 year old me was graduating from dial-up bulletin boards playing L.O.R.D. and downloading various items spread into dozens of megabyte sized RAR files. Obviously, networks had existed for a long time, but the early 90s saw a marked expansion of the casual public using the internet.
Are historians going to be able to study and explore what internet culture was like at those times? How daunting is the explosion of documents and simultaneously the lack of permanence to many of those documents? Is this a whole new field that is opening up?
a lot of the internet is preserved at https://archive.org/web/ (the Wayback Machine). This makes it easier to research than a lot of history, which has much less preserved records. Really, there's so much data that that can be a problem. You can't recreate any watercooler conversations on December 9, 1941 in New York. But you can access at least some conversations on the internet on January 20, 1993, if you want. But, yeah, it also faces challenges. But those challenges are the same as historians of other eras face.
