You do however build up a tolerance to modafinil, and it has various negative side-effects. But I agree that it's weird to make some sort of hard separation between various types of nootropics, and say that you should never touch some. Everything potentially has its use, and I think that Gwern covers this topic exceedingly well at his site.
