This is a good point, and being a great businessman is different from being a great engineer, and Zuckerberg is clearly the former (at least, and with the talent to be the latter). If you're a great businessman, you'll hire people who are, technically speaking, better than you are. If you're the best person at your company, that's a sign that you're doing something wrong. Zuckerberg also never had time to become a great programmer, since Facebook took off when he was 21-22. So he may have been, at that point, a "mediocre" coder by 35-year-old standards, but he was excellent compared to his age. If his coding skills haven't improved, that's because he was doing something else. He also seems to be improving himself, which is rare for business executives. Often when people have that kind of success at a young age, they remain young and arrogant forever. He doesn't seem to have done that, and my opinion of him has definitely improved in recent years.
