This is one case where I would hope technology is a complete flop
i don't think we have much to worry about. if you stop to think about it, the technology of sexual machinery hasn't progressed much past the turn-of-the-century invention of the vibrator.
For some things, people seem to prefer the personal touch.

(FWIW: A quick check of Amazon.com shows that they will sell you a vibrator (several types actually), many styles of spanking paddles, or even an inflatable girlfriend, but no spanking machinery.)
