Is it more important to know how to repair a car or paint a picture? Is it more important to know how to repair a boiler or create a sculpture? Is it more important to repair a fridge than to sew a bag? If you don't know how to fix certain objects then you can't drive, you can't store food, you can't heat the water. Let's imagine for a moment that there is a black out and you can no longer turn on the TV, the fridge will not be able to turn on, the car batteries will not be able to charge. Therefore it will be necessary to do without everything that requires electricity and repairs. So what will humans do? Will they return to observe the paintings they have in the house and dream? No, because they didn't want to spend money to buy the paintings but only spent money on useful things. And art is not considered useful. But in the future all the appliances will be turned off and whoever has books and paintings will be able to dream. Everyone else will perhaps die of boredom.
