The conference on Human Enhancement Technologies and Human Rights this past weekend had many boring parts and a few interesting tidbits.
Many of the speakers were left-wing ideologues who seemed to be directing their speeches only to others from the same small set of left-wing academics. There were fewer libertarians at the conference than I expected, but still enough that it was strange how much of a disconnect there was between the ideology shown in the speeches and the ideology I knew from elsewhere that many people held but were being quiet about.
There was plenty of concern about whether increased control over one’s body would decrease diversity, but I heard little that enlightened me on that subject. There have clearly been many technologies that increased diversity, such as tattoos. There are some that have decreased diversity because there is a substantial consensus about what’s best (e.g. eyesight – it’s unclear why we should be concerned about a shortage of people who can’t see well enough to drive). Then there are a few traits such as degree of autism where there’s some uncertainty whether reduced diversity would be good. There are some pontificators (I didn’t hear anyone this focused at the conference) who think they know better than the masses what the right amount of diversity is, and that their opinions should be imposed on the masses. But the evidence for the pontificators’ expertise and the masses propensity to make mistakes is generally underwhelming, so I can’t find much reason to be as concerned about the effects of enhancement technology as I am about the desire to impose expert opinion on those who don’t want it.
Hank Greely pointed out that the letter of the law authorizes the FDA to regulate anything that could be considered a body enhancement, including clothing. So only the FDA’s interest in obeying the spirit of the law will deter them from regulating external enhancements.
One amusing report of unwanted side effects of an enhancement technology is the increase in sexually transmitted diseases in seniors following the introduction of Viagra.
Aubrey de Grey made an interesting argument that the most effective approach to convincing people to support a cure for aging is to persuade them that they are being logically inconsistent when they fail to do so. He has a point, but it’s weaker than he thinks. He gave several examples of problems that were allegedly solved by persuading society to be more logically consistent, but I generally doubt that’s what happened. One example was tolerance of homosexuality. I see few signs that logical arguments had much effect on that. I think the biggest change came from peer pressure, which became increasingly popular as gays became able to migrate to places where there were enough gays to safely start exerting peer pressure. Another factor was the shift away from the belief that the main purpose of sex should be reproduction. That initially happened due to changing circumstances (reduced reliance on children to support elderly parents). I’d say that has generally produced beliefs that are more inconsistent as people abandon the least convenient symptoms of the belief (e.g. contraception) but are much slower to abandon symptoms that are remote from their experience. I think similar theories could be made about some other examples he gave (slavery becoming more expensive to enforce when railroads made it easier for slaves to escape to a non-slave state).
