I didn’t know what “shared art” meant in the initial post, and I still don’t.
So the art of rationality are techniques that we share to help each other “win” in our contexts. The thrust of my argument has been that I think rationality is a two place word. That you need a defined context to be able to talk about what “wins”. Why? Results like there is no such thing as a free lunch. If you point me at AIXI as optimal I’ll point out that it only says that there is no better algorithm over all problems, but that that is consistent with there being lots of other equally bad algorithms.
If you took any organism on earth and replaced its brain with a perfectly rational circuit that used exactly the same resources, it would, I imagine, clobber other organisms of its type in ‘fitness’ by so incredibly much that it would dominate its carbon-brained equivalent to the point of extinction in two generations or less.
This would only be by definition. Which I don’t think is a necessarily a mathematically sensible definition (all the problems in the world might have sufficient shared context).
