I am a believer in the long term (and potentially now even the short term) safety benefits of this tech but I do worry about the social side of things. I really don't want the startup business model to set in where service X comes out cheap, kills the alternatives then drives the service quality down and the costs up. I also worry about the fact that this makes it even hard to travel with anonymity. I want to get from point a to point b and not be tracked. The idea that that will even remotely be possible with this type of service is laughable at best.
