Are you in a completely different world than me? Because even the CEO of Boeing is not an engineer. Larry Ellison The CEO of the biggest bank in my country holds a masters degree in business economics, but nothing related to finance, econometrics or risk management. The CEO of US steel is an accountant. Don't even get me started on the (non)education of some politicians.

Understanding the product is often important, but equally often it is something you can delegate to others. It's only the younglings that think intimate knowledge of the product is the hallmark of a great leader, because that is the only thing they themselves bring to the table.

Specifically the CEO is more like the figurehead of the company; this role is to present and "sell the value" of the company to investors, important customers and partners. So often it is not too worrysome if the CEO has a different background; sometimes this can even make sense.

What should worry one much more is if the leadership layers below come from a very different background than what the company's industry is.

I agree fully with your comment, but I wish to point out that Larry Ellison's was a programmer at the time that the company that became Oracle was founded by him and his co-founders.
