In high school, I had a number of friends with bumper stickers that read, "Drum machines have no soul." I never fully subscribed, in fact I had one, and I tried to play it like a blues musician might play a dulcimer, muddled, erratic, and full of awe, but I entertained the notion that electricity might bring with it spiritual vacancy. You just gotta beat the hell out of those skins to make anything meaningful, it would be said. Finger tapping just isn't nearly physical enough. A real man would never let some circuit board do what he could do better with fists and two sticks.
The worst part about the whole thing is that you can split through ear drums just by turning a knob. The locus of control is just too far away, something might go terribly wrong.
