I wrote out some paragraphs about how these are very incomplete and unordered but useful and blabla bla disclaimers and trading quantum information between superintelligences that'd seemingly been lost to the environment and trading between quantum branches and bla bla and how cosmological natural selection is relevant but Less Wrong ate it and I can't convince myself to rewrite it. So, here. My not-passive-agressive apologies for being schizotypal. The marginal cost of my efforts is probably higher than your model suggests, but I realize that nonetheless I'm promoting suboptimal norms for what does or doesn't get to count as a well-intentioned effort at communication. I accept all downvotes as justified.
