It really does need to be the younger generation of cubers making more videos. Not very coincidentally, many cubers are ending up in college, many of them being in top colleges, and some are already in very tough high schools, so they start losing time to cube, let alone make videos. We need people VERY young so that they have time to develop in speedcubing and start making videos early.
I'm teaching a group of elementary youngsters myself. One of them look EXTRA promising. He's shown a high interest for learning, which is just what is needed in a good speedcuber. He and I are bound to be good friends too. Maybe I can get him interested in making videos. (I know I couldn't make videos without help. I'm off to college in the fall!) I'll update you guys if anything works out with that kid!
Maybe that's what we need! A generation of older cubers to teach the very young kids out there! I'm sure some of them'll be interested.
