Poor guy, if he had just heard about gps and about modern cryptography!
Which was used for the atomic bomb.
Thanks for posting :)
See people like: https://en.wikipedia.org/wiki/Yitang_Zhang that produced good math at a later stage.
just to clarify, it would be an observation to say "Most Mathematicians produce their best work when they're young" or "Most gymnasts who make it to the olympics are young"
But to say that X is a young mans game is inherently discriminatory.
A view held by some seems to be that since even the empirical observation may "perpetuate" the situation, stating it is "problematic" in itself, but I don't suppose this is what you mean here.
And the irony of this entire writeup is that number theory is now beyond "useful", as the underpinning for cryptography and security in our modern systems.
Also, a lot is different since the days of Hardy.
At least, now I see where some mathematicians get their pretentiousness :)
As I see it, this is not too big a problem. Usually people get on a very narrow path and specialize in a tiny part of a larger discipline. There's a lot of new research being done in algebra, analysis, geometry, statistics, whatever; but as a researcher you are expected to choose a very narrow sub-sub -...-sub-discipline and ignore everything else. That's very much doable. An analyst who can't read number theory papers is not a rarity. Likely a rule.
