Maybe it's just my own history and confirmation bias speaking here (recently switched from startups to a Consulting business). But lately, the whole "bootstrap" movement is getting much more popular around here. More and more, I'm seeing articles and comments from tptacek, patio11, and others talking about how programmers could make vastly more money, especially by doing freelancing. I think the message is starting to sink in - the kind of people who read this site can start very profitable businesses, make loads of cash, and do this without the high risk of startups. No chance of a working 5 years and then striking a goldmine of an exit, but much higher chance of working 5 years and putting aside large amounts of money.
This pg article is a great one, and a very honest one too. To me it reflects the changing times, and the changing understanding of what a startup means. No longer, like in previous articles on wealth, is pg very clearly advocating that all hackers should be starting startups. This essay, to me, reads as a much more precise explanation of what someone can expect if they start a startup. And it makes it much clearer when people should not start a startup.
