That sounds damn frustrating. Would you be willing to share your area of expertise? At 17 YoE, I avoid the cloud and ML because it's hard to bring my skills and experience to bear, and also I have no passion for them. But I have also found there's a ton of C++ code out there; IME there's a lot of appetite for someone who can wrangle it.
Well, the technologies I've used are all over the place, but the niche is defense contracting. Until now, I don't think I realized that processing lots of data really fast locally (i.e., not in the cloud) wasn't more generally in-demand.
That's not exactly a small niche. Edit: Just saw your LinkedIn profile below, have you applied to DC area companies? I think you would have much more success in the DMV metro area.
