In our tech-driven world, the basic drive of society is to make life easier, more convenient, as frictionless as possible. I suppose it’s the nature of a service economy. You can talk to your friends (or total strangers) around the world at any moment. You can find any piece of information with a simple search. Any show or movie you want is available in your home theater (or on the bus or in your car). Lunch from any restaurant can be at your door in fifteen minutes or less. You can have your dog food and toilet paper delivered overnight for free. We already have self-propelled lawn mowers and self-operated vacuums. Self-driving cars are fast on the way.
