I think that it's too small. Consider the swathes of time that are examined in history books.
It all looks amazing and fast moving when you are living it, particularly when you are younger.
Is it growing exponentially? Personally, I'd say that changes at the margin are becoming smaller. I think that the difference between 1940-1980 is much greater than 1980-2020.
As an aside, it's funny how static music has been for years. There are numerous bands that sound like they would have been reasonably successful in 1970 (and visa versa). 1920 vs 1970 is a whole 'nother issue.
I vehemently disagree with this, but agree this is veering off topic, so I'll leave it at that.
The only stuff I've found which felt in the ballpark of spot-on were:
1) https://studio.ribbonfarm.com/p/the-great-weirding This was a fascinating series of essays that generally walks through why, after "Harambe" in 2016 or whenever, things seemed to have gone off the rails towards something new.
2) Cypherpunk movement's source docs. If I could bold, underline, and highlight this, I would. I have never read any group of literature/essays, especially with publishing dates in the 1990s, that more felt like a post-mortem on the 2014->2021 craziness than cypherpunk docs. I had actually wondered for a while where this core movement went, but the quick answer I've come to is cryptocurrency/e2e messaging projects absorbed a lot of it, and then the the writing often took a turn for the crazy/non-PC in the final 10 yards. But, they so accurately diagnose the growth of virtual communities and their pseudo-governmental influence, digital economy developments and all the second order effects, and so on and so on. If you're looking for people who really saw what was coming, this is the group. One of the good reads: http://alumni.media.mit.edu/~wex/panoptic-paper.html
