Ironically, in the early 2000's it was the opposite. Something did change though because I've seen the problem you're talking about.
One thing could be companies, recruiters, or manager looking for CS or CE degree specifically. Someone who is 60 outdates CS and CE. I'd caveat by saying most fresh grads don't actually know how to negotiate algorithms correctly. They leetcode like everyone else before the interviewing process. As I've gotten older I've developed more holistic understandings of some data structures and algorithms, but definitely not all of them. The skill I think I became more adept at was working through the logic of them more efficiently. That's the gift repetition gives though, I suspect. All that to say, if entities are overvaluing those degrees, it's an irrelevant requirement.
Another thing could be that most jobs are phrased, "CS, CE, or equivalent experience". As someone without a degree "equivalent experience" at times boiled down to, "Have you worked at a FAANG or on FAANG level problems?" It's a circular dependency unless you spend some time in growth companies or start ups that don't have these hard requirements. Again, it's another useless requirement because you either have the math chops to solve the problems in front of you or you don't. I don't need provenance to tell me that.
All that to say, I don't even imagine how old someone is when I'm looking at a resume. Most of my judgement relies on the interviewing process and whether you can negotiate a simple algorithm and some systems design. That's as data driven as I can get it right now, although highly inefficient, but inefficiency is worth the time for quality, imo.
