Prediction: human hibernation will reduce aircraft emissions
Human hibernation has made some strides recently. I think a year or so ago a Wired mag article said the only significant unsolved problem is shivering. They have a cocktail of drugs that makes hibernation possible apart from the fact that people shiver at low temps.
If they solve this, I will gladly prefer to be shipped as cargo on a sail boat or airship so long as someone tends to a heart monitor to ensure a few heartbeats per min or whatever is still happening. No more Gestappo airport security, stresses of delayed flights, screaming babies, people eating Camembert cheese within 5 meters of you. You age at like ⅓ the rate in hibernation (or something like that). I’d gladly trade a week of reduced useful lifetime in exchange for a later death (experiencing more of the future than otherwise possible). The idea of being able to easily flip the middle finger to Boeing would also be a nice perk. (#boycottBoeing)
