22 years were always long, especially when you are talking about the edge times just before there were massive changes.
Take for example 1913 vs 1938 in Austria. (Ok, technically it's 25 years, but it's not much more than 22 years.)
In this time span you had:
- Monarchy, Austrohungarian Empire, at peace
- WW1 starts (1914)
- Austria loses WW1 (1918), Monarchy fails, first Austrian Republic is created.
- First radio station goes live (1924)
- Roaring 20s
- The head of government makes a coup, declaring the Federal State of Austria (Ständestaat), a fascist dictatorship. (1934)
- The Nazis take over Austria (1938)
You can find similar periods of rapid change in every country. For the US look at e.g. the independence war or the civil war. Or the time before, during and after WW2.
Yes, we are in a time of somewhat rapid change, but neither is that unique, nor is it especially rapid.
And the comparison between 1890 and 1960 is entirely invalid. Much more changed in this time frame than between 2004 and 2026.
As with everything, don't take it as a gospel. It's a tool that can be somewhat beneficial in the right circumstances, and it can also be abused and lead to horrible results if used dogmatically.
