In an ideal world, the TSA would use smart security. (Actually, in an ideal world, there'd be no need for security. But in an ideal realistic world, TSA would use smart security.)

I don't see them changing so drastically anytime soon. But they can make small changes. NoS are a step in the wrong direction. Pre-Check is a step in the right direction. At the end of the day, if I can't bring liquids through security because TSA can't identify what the liquids are, can't differentiate between explosive and harmless, and can't recognize whether I'm a terrorist or innocent passenger, we have bigger problems. The fact that I need to take off my shoes because ONE person got explosives through in his shoes is problematic. Not just annoying security, but scary that this is the organization that we're trusting with out security.
IMO, Pre-Check (which is optional - no one's forcing you to give over more information) is a step towards smart security. We still can't bring liquids through. And we need to give over information just to avoid removing our shoes. But at least it's a start.
