  • I expect they will not be worth it as they’re too underpowered for your specific use case. (I’m assuming your use case is hosting complex physical similations for a major university physics department and the old computer you’re considering on Amazon is a used version of this one or something similar.)

    For my home server I use whatever old PC I have laying around already.


  • What’s happening here is single sentence from the conclusion of paper with the explanation and caveats removed is being cherry picked by another author who then uses it to pretend it means what he thinks it means and make spurious arguments. Pointing at the paper and exclaiming “Science!” isn’t a defense. The paper posits human anatomy and physiology that does not exist to reach their speed. It’s scarcely different than referencing a paper pointing out humans would swim faster if only they had flippers.


  • The claim that humanity with all the money, medicine, science, and effort placed into recruiting and training world class sprinters has only managed to achieve less than 70% of the potential top speed for a human and that someone could pop up in the next couple decades that could drop the world record by more than it has moved in the last century in one fell swoop is not plausible. Sprinting is too close to raw power output for this kind record movement and if your analysis says that it is then you need to go back to the drawing board.




  • All the charts on page 15. The ones where they extrapolate exponential improvement for a decade while only citing themselves. Their prediction is 15% annually for storage cost improvements in Li-ion batteries which they call ‘conservative’

    Our analysis conservatively assumes that battery energy storage capacity costs will continue to decline over the course of the 2020s at an average annual rate of 15% (Figure 3).

    Let us check if their souce updated. $139 for 2023? That isn’t a 15% decrease since 2019’s $156, let alone year over year since then, which would be under $90. In spite of last year’s drop that is still more than the 2021 price of $132. I don’t know what ‘on track’ means to you but it must be something different than it means to me.





  • Oh FFS, I clipped the word new. Of course it uses information in the prompt. That’s trivial. No one cares about it returning the information that was given to it in the prompt. Nevertheless, mea culpa. You got me.

    this is a ship of thesseus premise here

    No, it really isn’t.

    The pupose of that paradox is that you unambiguously are recreating/replacing the ship exactly as you already know it is. The reason the ‘ai’ in question here is even being used is that it isn’t doing that. It’s giving you back much more than it was given.

    The comparison would be if Thesues’ ship had been lost and you definitely don’t have the ship anymore, but had managed to recover the sail. If you take the sail to an experienced builder (the ai) who had never seen the ship, then he might be able to build a reasonable approximation based on inferences from the sail and his wealth of knowledge, but nobody is going to be daft enough to assert it is same ship. Does the wheel even have the same number of spokes? Does it have the same number of oars? The same weight of anchor?

    The only way you could even tell if his attempted fascimile was close is if you had already intimate knowledge of the ship from some other source.

    …when a heavily altered photo of something that vaugely resembles it’s original photo in most aspects, is considered to be a photo”

    Disagree.
