[credo]

I'm not sure what you're trying to argue against. My first sentence said (a) "ideas are generally not unique" and (b) "it is the execution that matters"

I didn't discuss whether the execution was spectacular or not and I didn't discuss whether the idea was great or decent.

on (a), as a matter of fact, this thread proves that the idea was not unique on (b), as a matter of fact, the difference between the guy who had the idea and succeeded and the other guy who had the idea can be boiled down to one thing. I also suspect that hundreds of other people had the same idea. Again, what distinguished them from the guy who succeeded is simple. One guy executed, the other guys just had the idea, but didn't execute (either because they were incapable of execution or because they had other priorities ...)
