Nice to see numbers put to this. I remember thinking through a bunch of tech/science that I was familiar with, and realizing that most (not all) of the fundamentals in every case were known by the early 60's, and we've been working out the (very important) details ever since. Nuclear, electronics, chemistry, biology, etc. plenty of counter-examples, I'm sure, but like once you know the structure of DNA and it's fundamental operations, the remaining discoveries will have a smaller impact.
