That's a fool's errand. The trick is to make sure your body is continually controlled by some kind of computer that will wake you up when a set of conditions is met, so you don't need to rely on future humans. You also need to make sure your cryopod is stored someplace where troublemakers won't find it and turn it off. The best thing I can think of is putting your cryopod in a lava tube on the Moon, powered by a small nuclear reactor or maybe a large RTG.

"The best thing I can think of is putting your cryopod in a lava tube on the Moon, powered by a small nuclear reactor or maybe a large RTG." And then hope nothing critically fails for centuries ... Unless we have perfectionized robots by the time you go into the cryopod, you might as well bet on humans. And if we "perfectionized robots", that do not fail all the time, we already would have a very different world.

  You could have multiple failsafes, and after a part of them fail, you dehibernate automatically. We have systems that work well with such approach - planes being the most notable example - multiple redundancies, and when sth critical fails, you land asap. Works most of the time.

    And then you wake up on the moon in a lava tube too early with a partly failing system and hope that everything else still somewhat works? With current technology level I definitely would rather bet on humans.

      Looking at current human society, I don't think that's a very good bet. If you wake up too early in a lava tube on the Moon, you then use the tools and spare parts you hopefully were smart enough to pack and repair your cryo-pod and then go back to sleep.

    > you dehibernate automatically You what now? :) I think you watched too many scifies and started to believe that the plot devices are reality. “Hybernation” is a thing in movies because the writers wanted to write stories involving humans and long space travel. It is not a working technology in reality. It might become one day, but your RTG powered cocoon is not going to invent and perfect it for you while you are asleep.

  Robots? We're talking about cryopods here, not something that needs a robot where you need to operate accurately in 3D space. It just needs an electronic control system to monitor conditions and control some machinery, similar to a washing machine or microwave oven. We already know how to make redundant computer control systems, like for aircraft. It's not that hard. They don't "fail all the time" either. Sure, your crappy Windows computer does, but no one with a brain uses that for anything safety-critical.

    And you would trust that thing "similar to a washing machine" to run perfectly well for centuries? And not that hard? Are you aware of Murphy's law? Basically, give anything enough time and all the possible things that can go wrong, will go wrong. So your windows powered cyopod breaks after 1 year at most. And your embedded tiny verified OS manages 100 years, hurrey. But dead is dead.

You wake up in the middle of the moon and then what?
