We shouldn't expect the centuries old philosophical/legal/procedural balance we've crafted between investigatory powers and personal rights to remain valid and correct in the face of a 99.999% decrease in the cost of surveillance and corresponding explosion in scope.

Naturally, authorities didn't object to the technological expansion of their power. It's up to us to figure out if/when/how to push back. Step zero is admitting that it actually happened, admitting that we should reset our heuristics, and calling out the ludicrous argument "this is how it's always been," because, well it isn't.
