In a slightly different situation, mid-40s, but even though I grew up with Commodore computers, programming in BASIC, Pascal, etc. I didn't spend my 20s in tech (yah, I know, missed opportunity). Anyways, back in it now, but instead of 25 years of experience in my mid-40s, it's 15ish.
I have not had it negatively affect me in hiring yet, but I do things like just eliminate the non-relevant jobs from my resume so they don't age me up, and emphasize that I'm able to learn things (I think fairly quickly), but also that I have a wealth of non-tech but important skills I learned during those years that give me a different perspective sometimes.
I do think ageism will (and is) slowly getting better as the first few generations pave the way. I don't know if I'll run into it in my career, but if so, I'll look for a company that values my age rather than views it as a negative.
