What will be the role of humans in society when AI and human-like robots take over more jobs?

In yesterday's discussion by @aaronoleary, there were a few thoughts about using robots at home.

In this context, several questions occurred to me.

For example, what will happen to the future of humans if we delegate most of the manual and mental work to machines? How will we handle our free time? How will people be rewarded?

In most cases, when people are bored, they start doing stupid things (or harmful activities) to relieve their boredom, while a few individuals try to find a way to occupy their minds with something useful.

Do you have any idea what that future would look like?
