Andreessen is completely right: Startups are overvalued, stuffed like Christmas ducks with cash they don’t really need, and since they’re staffed by inexperienced kids with no oversight, they’re spending that cash. This is a big problem, a big and obvious problem, and Marc Andreessen is right: We should worry.

But what he’s not saying is that all of these worrisome things are happening because he has made them happen. Marc Andreessen is warning us, essentially, about Marc Andreessen. It’s not a good sign when a man, no matter how large it would appear his brain is, tries to distance himself from his current agenda.
