There will probably be dozens of books solely about the topic of what has been said by the executive branch on Twitter. (How clever will all those snappy quips and one liners seem 15 years from now on the pages of the next David McCollough?)
It's usually the case that those who aren't passionate about history will primarily be familiar with the big picture marquee events without fully getting the nuance of the experience, but there are troves of evidence here for extraordinarily rich future histories.
I've noticed a disturbing trend recently where this is becoming less true than we'd like to believe.
Try searching for news articles about GWB's 2nd term. Try to find opinion pieces about it. Try to name (and cite) a dozen different important events directly related to his administration.
It's doable, but it's not easy. Google's got a really short-term memory these days (unless, of course, you're trying to debug a problem in Linux, in which case these forum posts from 2010 are sure to help...).
It's a big part of why I take the time to maintain the bookmark database I've got: I don't trust that I'll be able to find articles like this one in the future.
I go further than that - and I assume many do: For stuff I think I'll want to reference in the future, that I find important - I'll take a copy of it; ctrl+s or ctrl+p for basic stuff, other things I'll take the time and space to mirror (using wget or something similar).
Given that we've seen major portions of the internet literally shut down or "destroyed" over the decades, this isn't something one should find odd or overkill.
I too keep a huge bookmark stack, but sometimes I don't properly sort things, and just put them in a "general" location. Recently I started going back thru these bookmarks, just to organize some of them - and many of them were no longer valid; 404s were the norm. That said, in many cases having the bookmark name or description (and even the old URL) was useful to find a copy of the information, where it moved (if it did) or maybe somebody archived it. But in some cases, it simply vanished.
I do agree with your assessment, though - Google and the internet has this "short term memory" problem; a big part of that is the (now) dynamic nature of websites, which doesn't allow for easy crawling by some systems (like the wayback machine), as well as allowing the data to move or vanish at a whim.
I suspect it will go the other way. A generation raised on the total malfunction of the US government.
Terrible URL, great archive of Trump administration events
