Ageism is a cultural issue. Some cultures venerate older people, some shun them. So it will vary. There isn't one "tech" culture. If you're talking about tech companies in the United States dominated by white males, ageism has been (and afaik, continues to be) a cultural norm.

Changing a culture's norms is incredibly difficult. The only way I've heard about it happening is through massive pressure, from either a large social group vocally pushing against an issue (with consequences), or a large industry spending millions of dollars to advertise something (diamonds, washing machines) and exploiting some other cultural bias to do so. Cultural norms can also change temporarily (we all worked remote during a pandemic and productivity went up, but after that it would seem our productivity went down? and women became industrial workers during WW2, but after that apparently they weren't good enough?).

So even if the norm did change temporarily, you need continued pressure to make it stick. I have not heard of any massive cultural pressure to end ageism, so I would not expect it to end.
