Ageism is still relevant, and probably will be. I see - and experience - that, if a senior has more experience than the tech department altogether, then it will cause tensions.
Also, most of the self-appointed C* level leaders (rich kid or l33tcode warrior) do not process well if someone has more experience and/or does not agree.
As I learned when I rewrote 10+ times my resume, you have to hide your experience and age because anything over 8-10 years is just not relevant anymore, or causes ageism (even ATS/GPT/LLM/AI/BOT give you negative points for the age). I have experienced this firsthand, since I have 20+ YoE.
