The skillset needed to be a productive employee who is, say, a programmer is not the same at all as the skillset to run an entire business.
For example, skills with sales are far more important than actual software engineering.
Sales and, shudders, marketing. I am not joking. As much as I hate to say it, my personal opinion is that this is the 'safe' spot now.
Yes, but before you needed someone good at sales and a team of programmers, now you just need a buddy good at sales.
