I think this is a very good point and is definitely part of the reason why we have apparent ageism. This aspect is also compounded by the fact that technologies and paradigms are changing so fast - yes I know software re-invents the wheel a lot, but the fact that you were coding GUIs in the 90s, before some of today's 20-something developers were even born, really doesn't make you that much better of a React.js developer.

I'm not saying the kind of ageism thats being discussed here doesn't exist - the "brogrammer", "culture fit" kind of discrimination. But I think its probably blown out of proportion. Especially for non-bay area companies, it seems like whenever somebody talks about "tech companies" they are referring to a very specific kind of tech company that is really only a relatively small portion of the industry.
