Being fired from his own company completely destroyed him - and not because he's worried about the financial aspect, he doesn't need to worry about that at this point.
I remember watching him go though this and thinking to myself "Jeeze, I'm glad my identity isn't completely tied up with what I do for work".
With AI knocking on the door I'm surprised how much my identity and perceived self-worth is actually tied to being a "good" developer. But it's more of a slow burner than what my father in law got. So I at least have some time to mentally prepare for my new reality.
