I personally have no worry for the future generations of photographers. I worry a little about their technique, but not their enthusiasm. I took a walk with a young man (family friends taking a walk together) who held a small digital camera at arms-length to take in the sun coming through spots on the ocean. I could have wished he had a tripod, or that he caught the light from a more illuminating angle. But it was reassuring to see him experience the pure joy of capturing the scene before him.
At least two young men/women I know have an interest in film and recently got 35mm SLR's. Haaa, I just realized. I have black and white pictures of both of them, I remember now - the young woman at a friend's barbecue and the young man at the Eagle Court of Honor.
