Interesting post, thanks for writing it.

My thoughts on reading this:

(1) If we designate all the goodness of the world etc. (art, poetry) as "sentimentality", I think the possibility that sentimentality is evolutionarily adaptive/selected for is being a bit prematurely disregarded. I know all throughout the post from the beginning to the end you mention that sexual selection and kin selection, while they exist, don't fundamentally change the argument, but I think they certainly need to be considered. I mean, sex being pleasurable (that you list along with all the other features of goodness of the world) I think is pretty obviously evolutionarily adaptive (you don't need to involve sexual selection or kin selection). But I think even less obviously adaptive things can be explained through a combination of natural selection, kin selection, and sexual selection. I think the counterargument to this argument would be that these arguments (for adaptiveness/selection) can be difficult to falsify and might be "Just So" stories. But still, for some (perhaps most or all) things I think you can convincingly make the case that they are in some sense adaptive.

(How would you prove it? I suppose an evolutionary biologist would be able to better provide an answer, but if a behaviour is conserved over time, found in many species, evolved multiple times through convergent evolution, exists despite apparently obvious selection pressures against the behaviour, etc., I think these can be evidence that a behaviour must be adaptive in a perhaps non-obvious way. Obviously ants or wolves or whatever aren't writing poetry, but they have complex social dynamics etc. The biggest distinction is that ours involve language, but I think the only reason other species' complex social behaviours don't involve (our form) of language is that they just haven't evolved capacity for our form of language. (Side note: our AI successors seem pretty certain to have language)).

Things like emotions, people like to contrast those with some sort of purely cognitive mode of behaviour. But I think emotions certainly are selected for/adaptive. They are useful for a variety of purposes: making behavioural plans coherent (e.g. making them consistent w/r/t approach vs. withdrawal, among other things); communicating our intentions to allow for social coordination; eliciting social responses; etc.

(I guess to the broader point about necessity vs. freedom, I'm not sure how distinguishable they are in the most cosmic of senses. But I mean in a more obvious day-to-day sense, about not wanting to work at a crappy, dangerous, demeaning job in order to survive, there is certainly a distinction)

(2) re: “imagining a beautiful, complex robotic ecology, robot poetry, robot sex”.

I guess when I think about the above, I think having a complex web of social interactions, complex social communication, emotions etc., is our evolutionary birthright and probably in some sense an inevitable outcome of us being intelligent. I don't know, it just Feels Intuitive that our future replacement robots (lol) must be creatures that will have complex social dynamics and make something like robo-poetry etc.

I guess this is all kind of an argument for complacency or that everything's going to be fine or something. But maybe it will.
