I don't see a very compelling argument. He is worse at using computers than his son. He says "I’m sure people are working on it." about Facebook's limited lifetime and the company extending it. The one rational thought I see is that he did not invest in Facebook directly, but rather into Goldman, who is likely to make out while others lose. But I am not at all compelled to try to get Facebook stock after the IPO, based on this interview.
Quote: "While a good idea is not really hard to find, finance to support those ideas is difficult. I have an aura, a business man’s aura. People know I’m conscientious, and I will make investments."
Doesn't exactly inspire confidence in his business acumen.
