Well, part of what I get from PG's writing is that "business" is something a hacker can figure out, and that perhaps it's better to get technical people on your team, and figure out the business stuff as you go, rather than try and find someone who "knows business".
I agree. However, I would suspect that having at least one hacker who enjoys the business of startups is important. If all of the hackers hate dealing with business, I could see that being a potential problem.
On these lines, an interesting hypothetical question is what would Apple have become if founded by 2 Wozniak's? Woz loved to hack, but strongly disliked the idea of starting a business. I think it took a Woz + Jobs to make things happen, personally.
Sometimes that is true. I know business and there are many times that I wish I new how to program. It's definitely not black and white. I really think you need both.
I got a lot of reaction from programmers looking for a co-founder that had good business sense. PG probably has a lot of business acumen naturally.
