I've been in and around the silicon valley since the late 70's. Hiring engineering talent has been the single biggest issue since then. I have yet to observe ageism anywhere I've worked. What I have seen is techies that fail to keep up with the industry and complaining that they can't find a job. Skills and experience have a short shelf life. 30 years ago Novell CNE was a hot ticket. 20 years ago people with CNE's started complaining about ageism. It wasn't their age, it was obsolete skills that made it difficult to find a job

And don't forget this page is based on html tables. One for header, one for menu, one for page content. This approach was discredited about 10 years ago. And 200+ Javascript LOC just to harvest form data? This guy is not a genius

My first software engineering job in the silicon valley was in 1978. I've been in and around the valley ever since in both engineering and project management. I've yet to see a bias against older programmers. I'm nearing 60 now, and I certainly have no issue finding work. I work for a small startup in the cloud application integration space. I would guess the average age of the engineering team is closer to 40 than 25. While I've never seen age discrimination, I have seen programmers who let their skills stagnate complain about age discrimination.
