Interesting. The main thing that pops out for me is that it feels like your story is descriptive while we try to be normative? I.e. it’s not clear to me from what you say whether you would recommend to humans to act in this cooperative way towards distant aliens, but you seem to expect that they will do/are doing so. Meanwhile, I would claim that we should act cooperatively in this way but make no claims about whether humans actually do so.
Does that seem right to you or am I misunderstanding your point?
Agree-vote: I generally tend to choose work over sleep when I feel particularly inspired to work.
Disagree-vote: I generally tend to choose to sleep over work when even when I feel particularly inspired to work.
Any other reaction, new answer or comment, or no reaction of any kind: Neither of the two descriptions above fit.
I considered making four options to capture the dimension of whether you endorse your behaviour or not but decided against it. Feel free to supplement this information.
