PG: I read your essay and most of the comments/remarks across the Internet. In my experience starting at a company, junior hackers learn from senior hackers, most of the problem solving skills I have learned was from other hackers (often more senior than myself). Even learning what not too do. If young hackers starts companies, who do they learn from? Do they just learn these problem solving skills and people skills by themselves? I am sure YCombinator has something to do with this process...
