So I was browsing the internet looking for stuff on speculative evolution - yeah, I'm a nerd - and I saw a hypothetical depiction of the human race in the year 1,000,000 AD (it's this if you're wondering). So that gave me an idea: what about a story focusing on a civilization that has totally lost its "humanity", and has simply regressed to mindless drones which rarely, if ever, practice conscious thought. Or maybe it could be more of a pseudo-essay, along the lines of Don't Be So Afraid of the Dark, but I feel like that wouldn't be effective enough.
So does anyone have any thoughts?
