Do not worry. Your every day startup may not (because their teenager culture), but the enterprises of the world love you. I am now crossing in my mid forties, being a paper dragon (architect) I still outperform the waste majority of developers in our groups. I have their respect and they have mine. However, idle you never can be. Because being of age and not being able to run with the pack is bad. Luckily, it is not the framework of the day but more the soft skills which make the difference.
