Did the idea behind Twitter, Facebook, Google, Wikipedia, etc change overnight? Yes, startups do often change their idea overnight, and that shows that the original idea wasn't great, but that doesn't mean that there are no great ideas. By the way, the "good ideas are evidence of how smart you are" is a bit BS. If all the VCs and/or YC cared about was that someone was smart, and since there are tons of other indicators (where they went to school, how many other successful startups they had, other smart people say how smart these people are, etc.), then if the VCs and/or YC knew by some other indicators that a group was comprised of very smart people then they wouldn't need to know what the idea behind the startup is. The fact that VCs and YC always ask what the idea is behind the startup before funding it, even when they know the team is full of very smart people (e.g. from multiple successful previous startups), it means that they don't just use your ideas to gauge how smart you are. They really do care what the idea is.
