I think you hit the nail on the head here. TECHNO is short for TECHNOLOGICAL. Its essence is its ability to advance with new technology, hence why all electronically created music was called techno back in the day. Personally i love vinyl and i am saddened to think that it might die but the point is that techno should advance with new technology and eventually artists won't be releasing vinyls (due to the limitations). So software like ableton is the way forward. That being said, it doesn't mean that other formats are wrong or bad, they're just outdated. There will come a time where people who still spin vinyls will be refered to as classical djs. I definately agree that theres something special about having a vinyl of your favourite tune in your hands which you cannot recreate with mp3 and I'm gonna keep building my collection, for the sake of having a collection of vinyl.
