Strong article. I think fear of technical ignorance is scar tissue. It's an overcompensation of the fact that traditionally programmers were undervalued until silicon valley proved that software does matter and is in fact a place where talent and decision-making power are incredibly important.

But in the end, technical knowledge is just one pillar. You also need strategy, management and ops to build a successful company. Rarely can one person bring all these to the table, instead you put together the right team of founders and employees to cover the essential skills. As long as you have a strong tech team whose knowledge and wisdom is feeding into the core of your decision making process then I think a CEO with more hard business experience is probably an advantage. It depends a lot on the company though.
