I think you're missing the point of the article. He's not talking about starting a company, he's talking about employee poaching (or lack thereof) by large tech companies, and its effects on engineering salaries. But as an aside, I definitely agree about selling. There seems to be this disdain for MBA/business types that don't build. As an engineer I can tell you that I have the utmost respect for skilled salespeople and I would definitely want one on my side when starting out.
