They would chuckle when they realized how instead of seeking to replace $8/hr labor to do simple tasks with fancy robots, we instead decided to focus on telecommunications and mobile computing, and now anyone can buy a smartphone for $800 that has a 120 fps HD+ screen (inconceivable to someone in the 60's) that can download 100mbps (inconceivable) almost anywhere in the world (inconceivable), record 4k/60FPS HDR video(inconceivable), store 1TB data (inconceivable) buy anything in the world and have it delivered tomorrow (inconceivable). We've built far more interesting and useful things.
Furthermore, It's not that we can't, we just don't want to. We like interacting with the world around us. Most people enjoy cooking, cleaning our living spaces, etc. As it ties us to the world. If we outsourced this to robots, we would maybe save some time, but then have to deal with robot repairs and troubleshooting.
Which would you rather do: Make dinner on a lovely Le Creuset pan or troubleshoot your Super Cook-a-tron 3000 because it broke down again?
