How many techie types have had someone come to them and say something like "Hey, you know tech thing XYZ? You know how it sucks? Well I've got a great idea: make a BETTER one! So what do you say? You whip it up in an afternoon, I'll handle marketing, and we'll be rich!"

Like they really thought that the issue is just that no-one can see the flaws. They thought that the fix is super easy and they're just the first person clever enough to see it.
