There are gobs of anecdotes from experienced tech workers about employers discriminating against older folks. I Googled around looking for more rigorous data, and found that there seem to be a decent number of studies of various kinds that detect ageism in the tech job market. One report (https://www.visier.com/clarity/four-common-tech-ageism-myths-debunked/ https://www.visier.com/clarity/four-common-tech-ageism-myths...) says it debunks four myths about ageism in the tech job market, but even that one affirms that hiring practices in the tech sector discriminate unwisely against older workers. So I guess we can tentatively conclude that, yeah, there's probably some ageism in the tech job market, and it will probably tend to affect most tech workers as they age. My own experience tends to agree. I was in high demand through my thirties. That demand began to dry up in my forties. I'm 61 now. I remain happliy employed as a consultant, but the people who employ me have shifted over time from mostly strangers to mostly people who already know me, or who know someone who has employed me before. To put it another way, as I've aged, my employers are less and less likely to be strangers who hired me in a typical tech-industry hiring process, and more and more likely to be someone who has seen my work before, or who knows someone who has. Maybe that suggests a workable strategy: take care to cultivate lasting constructive working relationships as you go. Look for people you work with well, and consciously choose to work with them, and to maintain friendly relations after each of you has moved on. Those relationships may become increasingly important to your work, especially if you begin to experience the ageism that many are reporting.
