It wasn't silly at all. What he was saying was that the set of all single founders has a higher bozos/nonbozos ratio than the set of all cofounders. That doesn't mean that the absolute number of non-bozo single founders isn't high, but that requiring a cofounder might be a useful heuristic. Additionally, it may have something to do with having the ability work with others. If you're investing in a potential company, you want the company to grow, so presumably it's not going to be a one man show forever. In this case you want to make sure that your founder can work with at least one other person. I personally think I fall into both the bozo and the "not being able to work with others" category. If I get to the point of having a prototype, then I've unbozofied myself, and perhaps could attract a cofounder. And if the cofounder works out, then maybe I have a shot at actually working with people and consequently running a company.
