Building a Pause Button for Biology

It's a really hard problem. Current approaches do excessively lethal damage to the human being suspended; the only hope is that future medical technology will be able to repair that, but 'future' still means 'post-singularity' or so.

Admittedly that doesn't feel as far out as it used to. But since I'm not competent to comment on the actual contents of this article, here's a thought instead:

The more advanced our suspension technology gets, the less damage it will do. Simultaneously, the better we will get at repairing such damage. This culminates at a crossover point where reviving someone who has just been suspended becomes feasible.

After that point, you can imagine our repair technology will keep getting better; and older and older patients will be revived and healed. So, you can imagine a chain of revived patients learning to live in whatever completely bonkers future world this is going to be -- because future realities are always bonkers, from the perspective of anyone who didn't live the years leading in to it -- and teaching each other what to do.

There's probably a science fiction story in there somewhere.
