"Basically you can do two kinds of products: evolutionary and revolutionary. Evolutionary products can start as something simple and evolve into something more complex. They are the ones we usually talk about because they are easy to do, and make up the bulk of all digital products." That's not true at all. Complexity has absolutely nothing to do with whether or not a product is revolutionary or evolutionary, that's just from the idea(s) behind it. The Apollo program DID launch early and often. In reality, the R&D behind it began long before we decided to send people to the moon.
