Asymptotic Burnout and Homeostatic Awakening

This is an interesting delve for a number of reasons. The ideas are worth considering however unlikely to be the "reasons".

I think human individualism (consumerism, liberality to consume as much energy as can be paid for, etc.) is unique in contrast to how other civilizations will likely behave. Those points about information and "energy" are worth considering in a wider sense (I would say "potential" and use the word "capacity" where the authors say "free energy".)

I think civilizations will only use radio broadcast in a limited sense and then for only a few hundred years of their progress. Once serious space faring is possible, they will have mastered the quantum dynamic allowing undetectable communications topologies.
