Indeed. As a former non-technical founder (now semi-technical), the worst part of the fear of failure is that your "job" is keeping companies alive. If your company dies, not only is your company a failure, but your only "skill set" is called into question. Knowing that fact and simultaneously being unable to contribute directly to the product, wondering how hard you can push your technical co-founder/team (or how far is right?) is enough to drive one insane.
It was easier (and more beneficial) for me to learn how to program. I'm not the most technical one on the team, but at least I can pitch in and work instead of wonder.
Similar position, I see start-up memorandums by full or mostly tech founders in which their common concern has been around building the wrong product or not knowing the customer. Yet being a 'non tech founder' or even 'semi tech founder' raises red flags.
