Like most government positions, I'm not sure I would trust anybody that actually wants to take that position. It's going to skew heavily towards either activists or the corrupt.
In theory, anyway, I'd push for appointing people to such roles by sortition, although that would never work in practice. Politics as a duty rather than as a career.
There's plenty of people with the necessary skills outside of the private sector or outside of the SF/SV tech bubble. The key will be how they select the experts, if it's a revolving door from FAANG then we know it was all a sham.
Sortition from what pool? I'd favor educating congresspeople (and citizens) but where's the incentive to make that happen?
