You know the ones who are just sitting all day in front of a monitor drinking milkshake? We already have VR headsets so we do not even have to look at a monitor. It can provide us an alternative reality that is to our liking. I am not sure how we could stay healthy that way. Maybe instead of milkshake we can drink the shakes made by health nuts?
Couch surfing never made anyone healthy, and invariably had detrimental effects on their health and life-span. Wall-E is literally cartoon fiction, so it's best to leave it at that. Just imagine plotting your next moves based upon observations of some episode of Tom & Jerry! You'll have better luck with The Simpsons though.
