I'm not a founder though, I'm employee eight billion at Bank of America. It's just that hiring people that are bad at programming is so demoralizing that it's better to not hire someone unless you're 100% sure they will turn out awesome. Otherwise, you'll spend all your time "helping" them, and neither of you will get any work done. (Nobody ever gets fired because it makes you look bad, or something, so if you make a bad hire, they're here for life. Especially since they are getting paid above market.)
