@Doug: By the logic of shutting up and multiplying, it does make moral sense if your life is that awful, you've got strong enough confidence in both the preservation process and that someone will create a Friendly AI to revive you, and there isn't anything left you can do for other people.

I mean, if I was wrinkling up like a prune from old age and my brain was rotting to the point where I had nothing special left to contribute, I'd prefer to be cryonically suspended immediately rather than wait another 10 years to die of Alzheimer's.

However, under the present legal system, all suicides get autopsied which is incompatible with cryosuspension, not to mention many life insurance policies. So no, you can't actually do this.

Though if the world manages to continue that long, it's a law that I hope will change before I get an opportunity to die of Alzheimer's. They might be able to retrieve lost memories after bringing me back, but the dying process doesn't sound like fun. Regardless of the morality, it's a fact that death doesn't scare me nearly as much as old age.
