As someone who transitioned to tech from finance, I can tell you that this trend (preferring young workers to old) is not limited to tech. The fact is companies in general are going to prefer younger people for labor. Younger people are cheaper, tend to have fewer obligations outside of work, and are willing to put up with more on the job. As someone getting older and more experienced, you can take this one of two ways. (i) You can try to "learn new tech" and "stay up to date" in an effort to compete with these younger workers or (ii) you can actually listen to the market. And what is the market telling you? Yes, younger workers are more valuable for the aforementioned reasons. But it's also telling you that by the time you are 40 or 50, you should be implementing your own ideas, not someone else's.
