--You only take a job in business operations if you aren’t smart enough to be an engineer (or designer, or product manager, or…)
--If your role isn’t technical, you don’t actually understand the product.

In fact, I would argue that good business operators have it just as good, if not better, than most engineers right now. Startups like Uber, Postmates, Airbnb, Dropbox, etc. are killing it, and they all have really talented (and highly paid) people in sales, ops, marketing, support, etc.
I think most of us are aware that it takes more than engineers to build a company:
