Yeah, I just thought you might have been being sarcastic haha.

I agree that burden of knowledge probably isn’t that big of a factor tho. I just chalk it up to there being less “unknowns” or incorrect ideas that need to be disrupted then there were in the past. It’s similar to how the rate of new “land discovery” has slowed down since the days of Christopher Columbus as well right? It’s simply because we’ve discovered most of the land on Earth and now it’s hard to come by new undiscovered areas. Exact same thing is happening with science most likely.
