I think jayohjo summed it up pretty well: "Come back in 50 years, and I may be good by then."
There are young musicians around who are technically brilliant. In time they'll turn into great musicians, if they keep at it. But the assumption that the peak of creativity is with the young just doesn't apply in folk music, it's something imported from a pop scene which isn't primarily about music at all.
Right now while they are young they need to be flash maybe, but that's no harm, in fdact it's great, so long as everybody doen't buy into the idea it's all about that.
The key thing about this kind of music is that the real heroes are mostly in their 60s, 70s and 80s. So long as that is true, we'll be all right.
