Since I don't play anymore, I guess this will likely be my only contribution to this discussion.
Notwithstanding his, um, unfortunate - yes, 'unfortunate'; that's the word I wanted - personality, I do actually think the OP has raised an interesting discussion point about the future of live performance.
Whether his aggressively monochromatic outlook on the subject will cut any ice with the old lags dotted around this place is another matter entirely of course. Then again, maybe he's not speaking to the old lags (or at least if he is then he's probably whistling at the wrong dog).
Shame really.
