I can see this being a serious issue on a personal level as well. In fact, it directly relates to the article, as this could be one of the things the newly awakened would struggle with.

I've considered cryonics for myself, but being relatively young still, I haven't looked into it too seriously. That said, if I did eventually go through with it and it did turn out to work, I could see feeling massive remorse for all the people I didn't convince (and financially support if necessary) to do the same. If I do decide to do it, I would certainly try to have my wife and children do the same, but what about my parents? Or my wife's parents? Our siblings? And then what if my kids only go along with to humour me, but their (future) families don't? Not to mention friends... In a sense you would feel like you let all those people die, because you knew of something they could do, but didn't do everything possible to see it happen.

Of course, even if that's how it felt after the fact, ex-ante it's far from a sure thing. Even the most optimistic likely see it as a significant long shot. And even if you were particularly confident, pushing freezing on everyone you know would basically make you the scientific equivalent of a religious zealot.

Still, more than just waking up having lost most or all of the people you know, you would be dealing with that, and the knowledge that their deaths were preventable. That would be tough.
