Now I'm reading the other comments and laughing at us all! “Have you ever read… have you ever read…?”

I'm imagining a weird paradoxical world where there people in the underground are unhappy and lethargic, and the people in the lawnmowers are happy and busy, and you're allowed to move wherever you like, and the driven kind of people end up in the mowers and the listless kind of people end up underground. And then, something happens and the mowers become self sufficient and the driven people inside the mowers fall into a rut because they have nothing to do, and then they end up discovering art and music, and move out into the light, and center their culture around the mowers, and decorate the mowers so they are just grass-mowing sculptures, and then some God-like figure comes back and is amazed at what happened to his people, and then decides to let them alone and continue to watch and let them decide their own fate.

Like I said, mind blown.

Have you read H.G Wells' 'The Time Machine'? Would the species on this planet end up like the Eloi and the Morlocks: one peaceful and innocent and the other brutish and cannibalistic? …or did you have anything else original planned for the species' characteristics?
