This guy springs to mind: https://en.wikipedia.org/wiki/Laszlo_Babai
Because, yeah, programmers and mathematicians don't actually need any experience, they can just think everything up on the spot!
I also wonder how you imagine that other professions gain their experience, if they don't need to think.
Maybe people in their 60s were not at the center of research, but I would say that the field was dominated by people in their 40s (certainly not by 20-something).
I cited the Fields medal, because their artificial limitation on age is one of the first things that comes to mind when talking about the subject
Same goes, ideally, for politicians and lawyers and engineers.
I've found that once you throw humans into the mix, nothing is routine. I think CS schools do their grads a huge disservice by creating the expectation that the coding is the hard part.
There are a lot of people who can reverse a linked list who can't coordinate a huge project, or build a product from the ground up that people care about. If those are soft skills (implying they're less challenging to pick up), why do most engineers only develop them after they're pretty skilled technically?
In my experience, it's not because they're forced to in order to make up for declining mental horsepower. It's because what you're calling the "hard skills" have become routine to them, and they want to do harder things than they can accomplish as an individual contributor. They want to do work that's less routine.
Why label soft skills as "not thinking"? Humans are way more complex than computers.
Perhaps English is not your first language because you sound like me at 19 explaining to my dad why I haven't finished his website lol
