In my perfect future, no one would have to eat. There would be capsules that would completely saturate and completely satisfy the nutrient balance. Food is an annoying topic for me and disturbs me immensely in everyday life, so such a pill would be the perfect invention. Without wasting time shopping for food, searching for recipes, preparing the dish, or eating, you would have much more time to advance your hobbies or important projects. This time saving could thus be used for further progress for society and can thus solve many other problems.
