The GFC didn't hit tech too hard. The places I worked pretended "times are tough" to justify not handing out any raises, but the place next door was always happy to pay more. I certainly was not feeling the same recession as my friends in other industries were.
Anyone that worked through the dot-com bust is late-forties, at minimum. But they'd have to be mid-50s or older to really feel the effects and know what changed. And people in their mid-50s+ are a strong minority in tech.
If the median tech worker is 32, they would have graduated college after the GFC was over (2014ish).
