That first statement "For people with more than 15 years of experience, there’s practically no correlation between years of experience and income" doesn't imply the second? Certainly there are possibly different dynamics at play wrt age, but regarding just experience as mentioned couldn't it just be that after 15 years you've gotten as good as you will get?

Edit: I read through the article, I believe these statement are not implying causation, just an AND.

That said, I don't think the editorial "tech is for the young" is really justified by the following statements, as neither is necessarily a bad thing.
