You’re acting like wearing a mask is the only trade you can do to prolong your life. But there are many investments/interventions into your own longevity that are more effective per dollar that you probably haven’t taken yet.
Do you spend more than two hours per day doing exercise? Do you check your micronutrient blood levels regularly? Do you refuse to go outside in fear of traffic accidents or muggings or skin cancer? Have you moved to an area with little air pollutants and good access to medical/cryogenic emergency services? Have you read everything on the internet that has a better than 1:100 million chance per hour of reading of saving your life? Are you always accompanied by your personal full-time physician?
Before you get to $1 per 10^-10 chance to preserve your life for the singularity, there are a lot of interventions you can take, many of which are expensive or time-consuming. Opportunity cost ruins it for all but the richest of people.
And that’s just regarding your own life. Other people have a chance of post-singularity immortality too, so rather than a small chance of saving yourself, you could go for a much larger chance at saving someone else. EA charities can manage about $1 per 10^-4 chance to preserve a life for the singularity, and investing in friendly singularity research is almost certainly even more valuable given your long-termist argument for self-preservation.
Real-world personal finance isn’t much of a red queen race. It costs an almost fixed amount of money to stay alive each year, and an almost fixed amount of money to raise a child to adulthood. If you make over $100k a year, you can comfortably raise at least one child and spend any excess money or effort on charity.
We’re probably not in a timeframe where evolution will matter. There are several existential risks and several technologies that render evolution obsolete that are likely to occur before most lesswrong readers would normally die. Having children for evolutionary purposes doesn’t seem like an effective strategy for promoting altruism.
We’re not at a stage of popularity where raising a child to hopefully agree with us to be charitable 25 years from now is a more viable memetic strategy than spending the years that would be spent child-rearing trying to coax people into taking off their earmuffs. Which in turn may be less efficient than just putting your nose to the grindstone and making a proof of concept child-saving robot to show off and use.
The camera crew and autobiography strategy is the one Peter Singer personally uses.
