No, the Teletubbies are the Eloi from The Time Machine. They are simple creatures that can't possibly understand the technology they use, so they don't make it or maintain it.
They freak out and go to bed when the sun goes down. Probably because the Morlocks are coming.
The world is far too technologically advanced for it to be Hobbits. The Hobbits are specially written to be essentially self sufficient and don't desire anything more advanced than beer (and magic fireworks.)
Cause using superman for his actual ideal use would be pretty boring for a comic book.
