Happiness is the only intrinsic value for a human being, and thus a moral person is a person who pursues happiness effectively. (How to do that is another story.) However, Aaronson's proposed definition of a moral person is not the effective way to pursue happiness. Thus, it is immoral. It's also immoral to call for all of us to sacrifice industrial output for future generations to solve the supposed climate change problem. There is no reason to presume that future generations are more important than the present generation (in fact, it is demonstrably the case that they are not). Thus, this position is profoundly immoral. However, the implicit assumption that sacrifice is moral is common to most world religions and also altruism, which is probably where he imported it from. All of them are morally bankrupt. A scientist shold be able to be skeptical and see such logical flaws, even if he is not able to propose the correct solution.
