Business does not equal mastery. if you complain about MBA BS then it should be obvious enough. The iPod was nothing new in terms of technical mastery. But it was innovative in terms of interface design, and a damn good example of successful marketing and integration into a whole product family; as such, it's also an innovation of process. But does an iPod engineer understand any AI? Probably not. Steve Jobs made stupid comments in his presentations (still remember the "branch prediction... it predicts branches!"). But he has an eye for opportunities that not even your professor can boast having. If there's a market, and you know what it takes to supply it, supply it. In my view, YC is addressing this; it may saturate quickly, but the need obviously exists. If your expertise targets the extremely educated, by all means make something that satisfies them. But don't forget that there are a lot of people to please. Just please the ones you understand, or think you do. I'm completely taken aback by twitter's success, but hey, people use it, what can I say.
