  • I read one of the papers. About the specific question you have: given a string of bits s, theyā€™re making the choice to associate the empirical distribution to s, as if s was generated by an iid Bernoulli process. So if s has 10 zero bits and 30 one bits, its associated empirical distribution is Ber(3/4). This is the distribution which theyā€™re calculating the entropy of. I have no idea on what basis they are making this choice.

    The rest of the paper didnā€™t make sense to me - they are somehow assigning a number N of ā€œinformation statesā€ which can change over time as the memory cells fail. I honestly have no idea what itā€™s supposed to mean and kinda suspect the whole thing is rubbish.

    Edit: after reading the authorā€™s quotes from the associated hype article Iā€™m 100% sure itā€™s rubbish. Itā€™s also really funny that they didnā€™t manage to catch the COVID-19 research hype train so theyā€™ve pivoted to the simulation hypothesis.




















  • Why when we look into the stars do we not see a sign of life anywhere else? Has life not emerged yet or has it wiped itself out? With what? Nukes? AI? Synthetic viruses made with AI? Who knowsā€¦

    entertaining this awful sci-fi schtick for a moment - if every civilization is wiped out by ā€œsuperintelligent AIā€, how come you canā€™t look through a telescope and see signs of artificial life? in this fantasy world shouldnā€™t planets taken over by paperclip factories be even more conspicuous?
