Anyone can accept risk. Accurately evaluating and effectively mitigating it is the skill, plus predicting a profitable direction and setting it in motion, maintaining accountability, negotiation and fundraising; the list goes on and looks very different from dev skillsets.
Maybe we need to see those skills map. I can't wait for CEOs to disagree that you don't need those skills. Most CEOs became CEOs because they started the company or are connected to the owners of the company. Most CEOs are just political leaders of a business. They didn't need to learn HR, Finance, IT etc in order to run the company.
Maybe this site should add a CEO skill map!
