The wearable cloud-storage camera linked by Bobbi here, as well as Google Glass, remind me of crude forerunners of the implanted Companion AIs in Sawyer's novel Hominids. It's got deeply society-altering implications, and I'm not sure I dig all of them very much, but they're implicit in the very existence of cheap, small cameras, wireless data transmission, and nearly free digital storage. (Similarly, I'm uncomfortable with the idea of strategic bombing of cities, but it's implicit in a world where monkeys can fly.)
In a society where everything is recorded and stored, privacy is dead, but so is the whole notion of "he said, she said," disputes, since what was actually said can always be retrieved. "Go to the data center and call up the files for Citizen Zimmerman and Citizen Martin." Creepy, and it will likely alter the very foundations of society in the probably-less-distant-than-I-hope future.
