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)
You will still be able to fly but the price will be much higher because the bigger market is in economy travel, which will eventually be people in hibernation moving along the surface.
That is probably decades from happening, at which point, I will either be dead or very old and won’t give AF about traveling all together.
