Even I agree this would be very refreshing for the scene that old guys start being slowly substituted by new upcoming talents. This could bring new fresh wind to things, but it will take time, tho. People will not start coming to club to hear unknown djs and acts, it will need some support from internet servers and media.
Then we are again on topic of taking risks and donating techno. Why donate it all the time???
One day, It must deffinitelly be succesful as old known techno names cant be gigging forever so no matter when the change comes, it will come, thats for sure. I hope we will not be too old when it comes, hehe.
