Cryonics appears to be the best hope for continuing a person's existence beyond physical death until other technologies provide better solutions. But despite its best-in-class status, cryonics has several serious downsides.
First and foremost, cryonics is expensive—well beyond a price that even a third of humanity can afford. Economies of scale may eventually bring the cost down, but in the mean time billions of people will die without the benefit of cryonics, and, even when the cost bottoms out, it will likely still be too expensive for people living at subsistence levels. Secondly, many people consider cryonics immoral or at least socially unacceptable, so even those who accept the idea of cryonics and want to pursue taking personal advantage of it are usually socially pressured out of signing up for cryonics. Combined, these two forces reduce the pool of people who will act to sign up for cryonics to be less than even a fraction of a percent of the human population.
Given that cryonics is effectively not an option for almost everyone on the planet, if we're serious about preserving lives into the future then we have to consider other options, especially ones that are morally and socially acceptable to most of humanity. Pushed by my own need to find an alternative to cryonics, I began trying to think of ways I could be restored after physical death.
If I am unable to preserve the physical components that currently make me up, it seems that the next best thing I can do is to record in some way as much of the details of the functioning of those physical components as possible. Since we don't yet have the brain emulation technology that would make cryonics irrelevant for the still living, I need a lower tech way to making a record of myself. And of all the ways I might try to record myself, none seems to better balance robustness, cost, and detail than writing.
Writing myself into the future—now we're on to something.
How many hours do you estimate you'll be putting into your autobiography for the resulting record to be "good enough"?
Next question, what is your hourly pay rate?
I see where this is going, so I'll go ahead and let you run an economic analysis on me. But, keep in mind that cost is not the only factor, only the main one for most of the world's population. For me it has far more to do with the social costs I would have to pay to sign up for cryonics.
That said, I estimate I'll be putting about 1 hour a week into writing myself into the future. I am currently paid at a rate of approximately $18 an hour. I'm not sure what my lifetime average pay rate will be, but let's go ahead and estimate it at $60 per hour in 2010 USD (I have two M.S. degrees, one in computer science and one in mathematics, and I'm willing to do work with questionable ethical outcomes, like "defense" contracting).
