Just steered into port...

Yeah, differing definitions of insanity between, say, the Negentropy Alliance and the Technorapture Hypernation are fascinating to contemplate. I especially think about psychologies that are looked down upon/pitied in today's world and how the social ecologies of the far future might support or even prefer them.

The differences between what some societies consider healthy is a great topic to explore. It's even the type of thing that the civilised galaxy may make a part of clearing customs upon travel. You'd want to be sure that you don't arrive somewhere that considers your psychology in need of healing.

Sometimes that juxtaposition is so compelling that I wonder if cryopreservation across millennia could be a viability in this setting, some eccentric or another setting their alarm clock for the Eleventh Millenium and finding themselves adjusting to vastly different standards. Of course, that might be probing too deeply into the near future, but maybe some plot devices could obscure any fatal details?

Many kinds of stasis exist in the setting. The easiest is simply uploading yourself and hitting pause. Hell you could upload and dial the clockrate of your mind right down, watch sunsets and sunrise flick by at hundreds of times per second. Someone practicing a lifestyle where they spend a few years travelling and then a few decades/centuries in stasis would totally work. The only thing worth keeping in mind is this would be harder in the early timeline (the first thousand years or so). Uploading was possible but for biological beings it wasn't easy to go back to a biological body, meaning the choice to do this would entail sticking with a synthetic body for a while. Also the very early timeline (i.e. the first few hundred years from the present day) did not have reliable uploading, backups, or even stasis. The latter was good but a risk, with a certain number of colonists in each interstellar launch dying on transit.
