General

could humans someday evolve into two separate species, one being super obese and another being slim? what sort of changes might the obese humans see?

I think we are getting towards that phase already. The super obese just continously eating into immobility with offspring being large at birth

I always figured that with the advance of automation, we could see a sort of robot takeover in the future, with machines and AI handling all of the work as humans, with no work left to do, end up becoming obese blobs who are too fat to function.

Exactly fat queens being serviced is the future of our species it is inevitable. Might as well get started and prepare for the future
