[Pinckney]

"The continuation and survival of the human race is the top priority among a large population of people. Some contribute by researching new medicines (Why do this?), others improve quality of life for others (Why do this?), others have children (Why do this?), and others look for a way to get us away from a potentially doomed planet in case of disaster scenarios."

The vast majority of medical research goes to diseases that pose no existential threat to Homo Sapiens. Even Malaria, which kills upwards of 500,000/yr, does not pose any existential threat. Late-life diseases such as alzheimers have no effect whatsoever on Homo Sapiens, yet receive substantial funding. No, medical research largely serves to decrease human suffering, a goal which I do regard as noble.

Likewise, why does increasing quality of life matter? Humans will continue to reproduce even in conditions of abject poverty. What does quality of life have to do with anything? (You, after all, seem to think putting humans in a thin metal tube and hurling them through space to live out their life on a cold, barren rock is important. Surely you don't think this would increase their quality of life).

As for children, I have no clue what people see in them. But they seem to reproduce because having children makes them happy, not out of some perceived obligation to Homo Sapiens.

My point isn't that you need to share my morals. My point is that you should acknowledge your morals are not universal.
