Why don't you actually read my comment? I said that old people with no achievements aren't going to suddenly become great entrepreneurs.

Jimmy Wales - extremely successful options and futures trader

Steve Jobs - I forget what company he was involved with before NeXT, but I think it was pretty big

Jeff Bezos - one of the top people at D.E. Shaw, right under Shaw himself

John McCarthy - programming languages don't really count as entrepreneurship, but I'm sure you could find many examples of old people creating languages

Marc Benioff - youngest VP in Oracle history

David Winer - I really have no idea what UserLand is

Larry Ellison - ok, fine. I guess if you're trying to make Oracle, it's ok to be old. I don't mean that as a slight to Oracle, but I don't think Oracle's story applies to web startups.

PG - I didn't say anything about old people not being able to become investors
