I disagree that dubstep takes less skill to create than other genres, especially when you see them doing it live. It's just much more reliant on technology than perhaps others are. I'd still rather listen to a good guitar solo than a dubstep rave though.
My point is that there is a lot less room for mistake with a computer than there is an instrument which relies on the human getting every little thing correct. The computer relies on the human playing the noises in the right order with the right time, sure, but so does every other instrument. There is much more pressure on someone who plays an instrument because they can mess up in a fashion much greater than anyone playing Dubstep can. An example is a Dragonforce tour that went horrifically wrong for Dragonforce some years ago. They were unable to play at the same speed that everybody knows their songs to be played at. This caused their fans to doubt the authenticity of their music and their abilities as musicians. They did manage to come back on their next tour and prove all the doubters wrong in the end, but I am hoping that you see my point here. I feel that it takes a lot more skill for them to play live like they do than it does for anyone involved in Dupstep to play live.
I don't believe that all Dubstep artists have no skill, I just believe that their level of skill generally lies quite low in the grand scale of music.
