  • In that sense, no underlying physical state could be said to hold “more” information than any other, right?

    In an information-theoretical sense, you can have a message that has a lower or higher information content. This is where entropy gets derived from. But it only makes sense for a fixed distribution – a more likely outcome has a lower information content. So I think you could have a physical state holding more information, if it’s a less likely state for some fixed definition of likeliness.

    This would probably be closer to an actual link between informational entropy and physical – a given microstate has lower physical entropy when it is a less-likely state (e.g. half-squished cup of coffee), and that state would have higher information content if we considered the state as the message. This intuitively makes sense, because physical entropy is in some sense the ability of a system to undergo change, so indeed a low-entropy system is “more useful”, just like a message with higher information content is “more useful”.






  • Storing a message in a system doesn’t make new microstates. How could it?

    Lol I got so tripped up by him later saying “this is no longer clearly 0 or 1 so it doesn’t exist” and decreasing N that I missed he does the reverse thing when encoding the message.

    This is like the ontological argument. He creates a virtual entity from words alone and then treats it as a physical thing storing energy. And then once it no longer fits the words of the definition, poof, gone it is, oh look, total entropy decreased.


  • We have to consider probabilities, not just for where the pieces are, but also for how they are moving.

    I completely omit that because, well, it’s hard, but also I don’t think it’s necessary here. This approach doesn’t work even if you consider only positions and assume uniformly random momentum. It doesn’t work even if the microstate is “is this pixel more red or more blue” in the paper’s experiment!

    But thank you for the comment, I’m glad I didn’t completely butcher entropy with my weird nonrigorous internal model I developed based PBS Space Time videos lol


  • but you aren’t quite right about some of the details.

    I’d be happy to be corrected.

    This isn’t too outlandish, and modern studies of quantum mechanics suggest that information is a conserved quantity,

    I hope I didn’t pass it as if it was completely out there, that information has to have some physical properties and energy as a carrier is a very reasonable hypothesis. The Landauer principle is not that controversial, I’m sad I’m too stupid to actually understand the discussion around it on any reasonable level lol









  • I don’t disrespect the dead (not conscious).

    To be completely serious, the only ethical reason for caring about the dead in any way is that there are living, conscious people that care about their memory and it would upset them. Otherwise there’d be zero reason to treat the dead with any more respect than other biological waste.

    All the other parts are normal and practical (why waste time or energy bothering animals or insects if you have no business in them? that hurts the ecosystem for no reason; why destroy your own useful property?), but if there was no ethical reason for not “disrespecting” the dead then we should, as a matter of policy, turn it all into fertilizer and put the unusable parts into a trash compactor so that no precious land or resources are wasted on cemeteries and shit.

    You can disagree with that, but I don’t see a way to make an actual rational argument against it without invoking consciousness one way or another.

    Just to be clear I don’t deride people who treat dead with reverence, you do you, although I think we could have a discussion about how much space is taken by burial grounds and the frankly gauche nature of some of the tombstones.


  • shall I presume many of you have no objection to being called ‘nazis’ in the standard twitter-left definition

    I didn’t know there was a standardised definition, or that it was somehow political-side-specific. If I were to steelman this then this could be about a pedantic distinction between a fascist and a nazi?

    Hey, you know what you can do if you feel bad about being called a nazi? STOP BEING A FUCKING NAZI.

    Shall I treat all drunk sex as ‘rape’ because kidnapper-rape and frat-sex have the commonality of reduced consent

    Yes. Yes you should. Hey, see, you understand this! Also consent either is or isn’t, there’s no “reduced consent”.

    Shall I treat your remarks about this-or-that group as ‘hate speech’, or ‘violence’, in the form of speech?

    Emm, depends on the remarks? If they’re hate remarks then ye dude, that’s what the word means?

    Clearly, we have some sense by which concept creep exists; by which definitions can be stretched dishonestly.

    Ye, like how you would define “censorship” I’m sure
