In my annectdotal experience the same people who tout wanting to support and hire from a diverse pool of applicants to not miss the next Einstein, don't extend that logic into the Unborn.

I think the way we are likely to solve our greatest issues like climate change through having more smart, well-educated, well-raised, and loved children. So if you're privileged enough to have the capacity to raise such children it's probably one of the greatest things you can do for the future health of this planet (and if you still feel torn about the overall population rate you can still apply this logic to adoption).

If all the altruistic people depopulate themselves, then only the least altruistic will remain.

I don't buy into this theory. We have plenty of minds currently and are failing to avoid and solve planetary scale issues. My take is that this is an incentive problem, not a lack of cognitive capacity.
