I think it’s more so because it took a long time to figure out the basics, and now we have them to build further upon. Take cars, for example. Can you think of any revolutionary cars from recent years? The first ever cars were revolutionary. The Ford model T was revolutionary because of its assembly and availability to the masses. The first few hybrids and EVs could also be seen as such. But other than that? Nah.

Perhaps a car enthusiast would like to correct me, that’s fine. I admit I know very little when it comes to cars. But this is my perception at least.
