This modern technology is having a run-away. Your grand kids run around with things plugged into their ears. They can't hear a word you're saying because they are listening to their music.
You have nine hundred TV stations to watch. You can get on line and chat with somebody that lives on the other side of the world. I guess the next thing will be to explore and visit other planets. I mean regular folks will be able to do it. Probably not until they find a Mall on one of them. When that happens the shoppers will find a way. It makes life interesting. Imagine if we were still trying to invent the wheel. We used to churn butter by putting the cream in a fruit jar and shaking the daylights out of it until it turned into butter. How exciting would that be?
