I think technical PMs are well suited to absorb this. Ideally, they're already comfortable with specifying software, communicating about requirements, recognizing and avoiding failure modes, etc. So that's one route, but not one that particularly appeals to me.
The things that I find interesting largely haven't changed. I'm interested in complex systems, distributed or not. I'm interested in organizational dynamics. I'm interested in game theory and mechanism design. I'm interested in simulations, machine learning, and GOFAI. I'm hoping that I can find a way to turn these interests into a new career. I can continue learning and growing, I can challenge myself, I can expand at whatever speed I can manage, and I can develop and deliver working software at a greater pace than I've previously been able to manage.
I'm definitely afraid. I don't know how to just create a career from a vague collection of things I like thinking about, to just go out there and make money and support my family. I don't know how to "operationalize" these ideas. But that's what I'm trying to do, FWIW.
