If you're not doing anything wrong, you have nothing to hide, eh?
I'm quite confident that anything I've ever said or done would likely not be of any interest to the scanning algorithms of the NSA. And even if that were the case, if I were to choose to have someone listen to a conversation I had, I'd rather it was some anonymous person in a basement in a desert in Utah whom I will never meet, rather than any friends, family or neighbors or business associates that were not privy to the original conversation. I stand by what I said. And I'm sure that goes for most people, excluding the paranoid delusional types, which are a dime a dozen in this forum.
But technology is obviously inevitable. Given that, you're likely to suffer more embarrassment, persecution, fouled relationships, business problems and neighborhood gossip because of technology enabled spying and media leaks (already here and/or coming soon) than you ever will from an NSA operation.
Technology is inevitable. It's use is not. Only the NSA has reason to spy on everyone.
