I think it will be a while, if ever, before we're able to handle passing types around as values, in Haskell, the way we do in Idris and Agda. Dependent typing isn't just some feature. It touches a whole other way of thinking about things.
If you go all the way with Agda, you have significantly constrained recursion to the point that the language isn't turing-complete anymore, but in return you get termination checking and other nice things. As it turns out, most of the code we write doesn't need unbounded recursion. Seriously, can you think of the last time you wrote something like that?
And I think that'll be a hard pill for people to swallow, much like how it was really hard to sell memory safety to C/C++ guys back in the day.
