Good luck not getting shot LOL It seems to me there are very few flesh-and-blood humans if any at all, so I assume they wouldn't take kindly to us. I think the entire population must be cyborgs at the very least, since robots would likely have no issues whatsoever living in tiny cramped slums piled high into the clouds like that. Just look at Bender from Futurama. Robots don't need much personal space to thrive. And I thought I would've seen at least one sci-fi movie emulate this concept, but the last one Elysium didn't even come close to this scale. I was actually disappointed in that regard. This world is so incredibly epic, but not a place I'd ever want to live for sure, or even visit for that matter.
