Then, at some point, being in tech became a gilded profession and everyone: salesmen, artists, clerks etc. joined in. Not because they wanted to be in tech.
They wanted gold.
For years it was working, but right now things shifted. You can no longer just do the thing you learned for a job and continue doing so, because landscape shifted. So they're miserable and they want to get back to knitting, pottery or whatever thing they want to do but not tech.
For people I know who are in tech for the tech nothing changed. There's new tech in town, one has to adjust, and it's still possible to discover new things and pave new paths. Tech was always shifting and I suppose people who worked in it for it always knew it, and it doesn't derail them.
