Agents which do not care even instrumentally about effecting the wider world probably will not predominate. They will probably be bystanders and NPCs—and by their own lights, this is fine.
I would point your attention to Rucker’s character Sta-Hi Mooney, from the Ware series. An inattentive reader of Software might consider this character a bland hedonist, and in the first sense he is. But through the novel it is revealed that he is very engaged in a Dionysian manner, the disruption of rationality provided by drugs gives him an awareness that is not available to “NPCs,” mere bystanders, or even the hyper-rational inventor of AI, Cobb Anderson. We see a Dionysian kind of character also in Fear And Loathing, where only Raul Duke can actually discern the mad American Dream. In a sense these characters are destructive, tearing down common illusions that we all take for granted, and in the case of Sta-Hi, we have it double in his destruction of the Big Boppers.
Rationalism or Apollonian thought is less capable of “play,” and I do not mean that in the sense that rational people aren’t enjoying themselves. Rather, play in the sense of Derrida where we are stressing the seemingly unlimited permutations within a limited system. This working out of a minmaxing strategy for making sense of the world leads to a very narrow and deterministic style, Narrative.
Apollonian thought is insidious, one may not even notice its narrative building blocks. This hunch that a Rationalist is better prepared for “instrumentally effecting the wider world” cannot be true, as the whole affair is bent towards the crystallization of ideas into more beautiful, solid, or eloquent terms. This is the opposite of transformative action. Ultimately, the destructive impulse of the Dionysian is a perhaps final reflection upon a thought and not a destruction as it poses, and what was once their new paradigm instantly begins to itself crystallize as rules of how to best play the newly-altered game arise. So its destructive mandate is not an end in itself, but a new beginning.
This dynamic is very evident in a lot of popular fiction, as well. When one finds oneself in a lose-lose situation, I think the slightly crazy and compulsive Captain Kirk is in order over rationalist Spock, the Vulcan most often convinced of his own narratives and a total defeatist. Contrast Gandalf with Saruman, the wandering unserious wizard who quite irrationally let the world’s fate hang in the hands of a few very hedonistic hobbits rather than the very logical Saruman who wished to build up his own power to betray Sauron.
There’s no need to strain a metaphor beyond its good use. The intuition pump as a surprise taste test could be more, a moral allegory as you’ve had it, but that’s the very kind of narrative thread-weaving which I wanted to warn against.
What I want to emphasize most of all, and I’ll be more direct and less clever now, is playfulness over minmaxing. Making and stockpiling increasing amounts of bows, ever more effective weapons, is not so much a metaphor for a game as it is the most immediate and serious existential threat to humanity, even moreso than the climate. If we’re at all wise to the world, similar existential consequences from AI are still quite beyond the horizon. Serious to be sure, but these tenuous long strands of allegory, metaphor, and tapestries of analogy, the very substance of Rationalism and logic, are basically unfalsifiable and therefore closer to the mythological.
OP is onto something in pointing to playfulness, taking the way of Gandalf rather than Saruman. Saruman’s way is precisely what Anthropic is doing, playing a defeatist game of ring-making, orc-breeding, and forest-burning.
