I am kind of worried about this myself. On the other hand, everyone I know over 40 in tech is making enough money to retire in less than a decade assuming some decent personal finance skills. It could be survivorship bias, but I think you’re fine. Even if you have trouble getting hired in 5 years, you’ll have a million+ in the bank to fall back on and retrain in something else.

I'm not there yet, myself, but articles seem to indicate that it's tougher. I would imagine that the problem is possibly even exaggerated here, though, where tech is as much of a trend and culture as it is a job, and people feel like they need to be on the cutting edge, new, and cool.

Any age, as long as your skills are current. The demand here is savage enough to overcome most prejudice. There are many times more older engineers in the bay area than anywhere else I’ve worked.

> Even over 40? I am genuinely curious.

It'll be tougher, especially if you are a white or asian male, but there are plenty of software jobs out there. You are less likely to be getting choice projects, raises, promotions, etc. And you are on the top of the list come lay off time, but you won't be on bread lines anytime soon as a software developer. But you will be marginalized as you get older and even more so if you are part of the overrepresented group in the industry.
