I've seen the quality of people who get EIR roles. They're not slouches, but I could do better than most of them, and that includes the ones at top firms. I can actually detect things like what kind of programmers your tech stack will attract; non-technical executives are better with general-purpose marketing, but the 10X factor with regard to programming talent is black-magic to them.
Even rarer than 10X programmers are people with enough experience and insight to know what brings "10X" into being and what smothers it. It's not just about the people; conditions and configuration play a gigantic role.
I've avoided exploring the VC route (as in, becoming one) because I want to keep my technical skills intact. Also, I'd be +5 sigma great at one part of it (evaluating technical choices and judging talent) but I have no idea if I'd be any good at the other (also critical) aspects of the business. I also feel like if I committed full-time to nontechnical stuff, I'd lose that +5 sigma edge. Right now, I know that if you're using Clojure and your competition is setting up the Java/Maven/IDE environment, you'll almost certainly win. I might not be able to pick that sort of thing out, in 20 years, if I step away from using technology on a day-to-day basis.
Right now, I could grep a codebase and tell you better than almost anyone out there if a company has the technical mettle it needs. ("Visitor" or "AbstractFactory" = bad, "mapcat" or "flatMap" = good.) I wouldn't have that if I sat out of the technical game for 20 years, because the signs and terms would be different.
