Well, don't scoff at wearable electronics just because they're mostly LEDs and NFC chips right now. If we can figure out how to make something both stretchy and conductive, there's a lot of practical opportunity. What if your knee/elbow/wrist/etc brace had a small alarm to go off when you start to overextend it during recovery? What if your jacket had a button to quickly mark precise GPS spots in the field for later follow-up inspections? What if your shirt could adaptively nag people about their posture during the 4 hours they spend seated every day? Heck, you could cobble the GPS jacket together today with off-the-shelf parts; it'd just look strange and probably be fragile/uncomfortable to wear. As for self-driving cars not involving 'real people and problems,' I just don't understand what you mean by that; could you elaborate?
