Geek's Wager would require me to argue, albeit slyly, that cryonics should be preferred over other entropy-defeating technologies.

There aren't any, at present, and so it's sufficient to characterize the set as not-cryonics because the set of post-mortem entropy defeaters contains only cryonics.

And, because it's, you know, a pretty good slogan that wraps the issue nicely.

But if there were other options, like uploads or maybe a plastination-like preservation system, I'd probably not say anything, especially not anything glib. I would no longer feel comfortable telling random people on the Internet where they should place their bets.
