I think you have to be more specific. I could totally believe that WRT to SV tech startups and other younger companies, but they often seemed focused on fashion and in some cases be places where only the young and stupid would be willing to work.

There are "tech-centered companies that" are different. For instance I work at a company that's basically evolved to be a tech company, and if anything, our development groups skew old.

Personally, I'm still worried more about outsourcing than ageism.
