Yeah, this ageism factor mixed with how unstable in general my industry is had me adjusting my long term plan to focus on being able to survive off my own products. I'm still far off from that point but it's probably best to plan my mid-late career before industry locks me out...

Doesn't help that I've tried to specialize for quite a while but simply can't stay around long enough without layoffs happening. Hard to be a domain expert when companies let you go ever 3 years. T shaped generalist it is, then.
