What's the rationality-related moral?

I asked myself the same question when my first impression was "Transhumanist/x-risk in-group applause light". The answer I gave myself was that that is is related to bullet-biting and shut-up-and-multiply.

The assumption is that the person to be inspired by this quote already has preferences for people not dying and for a positive future for the human race. But few consider those implications personally and act on them. Few consider it their responsibility or, if they do act, act to save individuals that catch their attention rather than doing something that does the greatest good (according to their own preferences).

Something To Protect springs to mind, as does Tsuyoku Naritai! (I Want To Become Stronger). "This world which God has abandoned" seems to imply/assume Beyond The Reach Of God although I'm not sure if that counts as "rational" in and of itself.
