I get your point. But I'd argue that a shortage in technical talent doesn't logically imply great engineers are more abundant than great sales/business people.

I get your point. But I'd argue that a shortage in technical talent doesn't logically imply great engineers are more abundant than great sales/business people. It's just that there are probably just more mediocre business people than there are mediocre engineers. At the pure idea phase, some degree of technical talent, however minor, is huge leverage, esp. if whoever it is can prototype something to a point of raising seed capital. At this point, incredible engineering skills aren't needed, but some solid technical background is important. That said, the degree to which engineering talent is required is really product dependent (as well as space dependent--i.e., consumer v enterprise).
