Tommy, yep things are a changin'. War may become an 8 hour job with desk pilots assigned a work shift. Just put on your VR headset, maybe from the den in your house, do your 8 hours surveilling or targeting the enemy in some remote part of the world, then hand off to the next desk jockey for his shift. Don't want to hijack this thread too far from the OP's intentions, there is a lounge thread this would fit into
As for self-driving cars, it could be that garages become obsolete or turned into dedicated hobby work shops. You call up your Uber like transportation when you need it. It drives to you, picks you up and delivers you to your destination, then goes back to a charging station "lot" where it is cleaned up like the cabin in a commercial jet then waits for the next call. Grocery shopping? - ordered and delivered all from the keyboard.
