There is an excellent book by David Mitchell "Cloud Atlas", showing from his point of view the consequences of such a "relaxation" of humanity. Quite an interesting hypothesis.
People stopped working and split into two camps: the highest grade, which are served by artificially created beings somewhere "above", and the lowest grade, which are hiding and trying to survive. With the development of technology, people of the highest class completely forgot what physical labor is, and the world as a whole sought to create something incredible. As a result of the impetuous efforts to make life, so to speak, an explosion occurred completely automatic, which threw humanity to the very bottom of development. It all started all over again: the development of agriculture, cattle breeding, hunting and gathering. Lack of technology and literate speech.
Scientific and technological revolutions have already taken place with the introduction of automation instead of people and, as you can see, it did not end in disaster. Because other jobs are being created, such as servicing robots. This will only lead to the fact that people will stop ruining their health in conditions dangerous to the body.
