Assume for the time being that it will forever remain beyond the scope of science to change Human Nature. AGI is also impossible, as is Nanotech, BioImmortality, and those things.
Douglas Adams mice finished their human experiment, giving to you, personally, the job of redesigning earth, and specially human society, according to your wildest utopian dreams, but you can't change the unchangeables above.
You can play with architecture, engineering, gender ratio, clothing, money, science grants, governments, feeding rituals, family constitution, the constitution itself, education, etc... Just don't forget if you slide something too far away from what our evolved brains were designed to accept, things may slide back, or instability and catastrophe may ensue.
Finally, if you are not the kind of utilitarian that assigns exactly the same amount of importance to your desires, and to that of others, I want you to create this Utopia for yourself, and your values, not everyone.
The point of this exercise is: The vast majority of folk not related to this community that I know, when asked about an ideal world, will not change human nature, or animal suffering, or things like that, they'll think about changing whatever the newspaper editors have been writing about last few weeks. I am wondering if there is symmetry here, and folks from this community here do not spend that much time thinking about those kinds of change which don't rely on transformative technologies. It is just an intuition pump, a gedankenexperiment if you will. Force your brain to face this counterfactual reality, and make the best world you can given those constraints. Maybe, if sufficiently many post here, the results might clarify something about CEV, or the sociology of LessWrongers...
The idea of wiping out other species to prevent their suffering strikes me as pretty bizarre. It's the same sort of extension of Negative Utilitarianism that leads to the suggestion that we should do the same to humanity, and I don't think that's a very practical approach to utility maximizing.
In any case, I doubt most of the natural world suffers nearly as much as the philosophers in that link suggest, partly because I suspect a lack of abstract awareness and other neurological faculties limits the ways in which most animals can suffer, and partly due to the same hedonic treadmill tendencies that exist in humans.
It seems like we have two disagreements. The first is whether there are living conditions to which death is preferable, and the second is over how bad the conditions wild animals live in are. About the first:
I'm not a negative utilitarian, I don't think suffering should lexically override happiness. I just think the suffering outweighs the happiness here because there is more of it. I definitely don't think humanity should be wiped out too. Humanity wouldn't otherwise be living in conditions worse than nonexistence, and has a good chance of living in bette... (read more)
