Let us work on the assumption that humanity creates a self improving and soon god-like AI which is truly only desiring to help humanity. Its vast intellect would solve problems humans can’t even comprehend. The drones it creates will tend to our every need. The AI will run the perfect government, manage the perfect economy, create the perfect art, our every need will be met without us needing to lift a finger. Our last invention means we will never invent again. We will never create anything again. All of our choices and goals are meaningless because the AI is vastly better and motivated to help us. It is certainly true that we won’t need to work, but this ignores that to a degree humans like working.
Right now in America we have thousands of college graduates sitting at home lamenting their lives. Money is certainly an issue but what they hate most is that the skills they have are useless. The movie Wall-E depicts this kind of future. Humans live hedonistic lives purely of instant and universal gratification. An AI system works behind the scenes providing them food, water, entertainment, even letting them know the latest fashion trends. Choice of course isn’t simply ripped away from them. There just isn’t any point. You won’t ever influence this society nor is there any real motivation to improve yourself since anything you will learn the AI not only knows already but has available to anyone if it was just asked.
