Knowing how rebellious kids can be (I sure was), you might be right, something worse is coming. It'll probably be a combination of disco and rap. What a sound... we can call it discrap.
The sad thing about rap is that it's essentially disposable music from throwaway performers. You don't hear rap oldies very often, certainly not on the rap video channels.
But I've come across examples of it being shoehorned into other music as a fill or bridge where it doesn't work too bad. Check this Olga Tanon offering out.
