If you are in the valley you are in an echo chamber. In the rest of the US the developer workforce is aging. I am 40 and as such we where the first wave of developers building the internet. We have aged with the career and you still see us around what you don't see is many before us and the reason is, there where not many before us and less that transitioned from old PC based development to what we do now.<p>The issue is far more complex than age discrimination, people look at the lack of examples before age 40 and the few of us in our late 30's and 40's and jump to age discrimination but the reality is there where just fewer of us back then, then the .com bust and the downturn ran a lot out to other industries and there is natural attrition.
Is over 30 an issue? I would think this is time to hit your stride. Often this is getting towards a decade of experience that can see skills peaking and bring a bunch of experience and know-how to a team.<p>Maybe surviving after 40. More realistically surviving after 50 is a legitimate question in my mind.
Imagine you are part of the next wave and keep your willingness to try new things. I have met many folks over 40 that are far more savvy than their younger contemporaries in terms of exposure to what is new and being paid well.<p>Edit: terrible word usage in last sentence
