Output Stream of Consciousness

I was musing over a theoretical invention that could cause society's downfall. No, it's not telepathy, though I'm sure that would do it.

If there ever was a device that let you hear what people said for the next ten seconds after you hung up the phone, I think that would be enough to do it. I'll bet technical support would be the first to fall :)

Well, unless people started watching their words for ten seconds :)
