I have no doubt there is some age discrimination, though I haven't experienced it personally. What I want to point out here is that there were a lot fewer of us in total when I first started (I'm 58 now). I find very few peers my own age now, but I also found very few peers my own age when I was 25. So just going by percentages may be misleading for a relatively young discipline.
I wonder about that, too, although I'm "only" 45. I still have tons of people pinging me with new job offers, and they don't look like the sort of job offers that they're going to offer a 25-year-old. Regardless, I put a lot of effort into making sure that they need me more than I need them.
