When all jobs are able to automated it will mean human intelligence, skill and labor has been surpassed by machines. We will be treated like pets in a world run by machines, like WALL-E. We will have no real autonomy or ability to determine the future of the world. There will no longer be any reason to try at anything, since all useful tasks will be done by machines and the only things humans will do is pass the time and experience emotions. But we know that people aren't happy unless they have some purpose. Goals, challenges, struggles. Depression is going to skyrocket if machines get to human intelligence.
