      Does it cut carbon by 35% or does the AI say it cuts carbon by 35%? Assuming it does, does the new formula substituting in Elmer's glue actually hold up?

      I've noticed a lot of people even really really high level people are trusting what it says waaaaaay too much.

      • The AI is still faulty.

        Limecrete and Hempcrete exist and are far better than 35 % , they are carbon NEGATIVE!!!!.

        Why did the AI not suggest this ?

        We continue to stay on the path to extinction.

          No.

          They do, and they are.

          Why did the AI not suggest this ?

          Because they have terrible compressive strength, and are generally used as insulation, not load bearing, what was not what they were looking for.

          We continue to stay on the path to extinction.

          The Earth naturally sequesters and emits carbon in the various carbon cycles of varying lengths.
          It's not quite so simple to point at any single carbon emissive behavior and say "that there- that's leading us toward extinction!"
          The biggest target needs to be fossil fuels. But in the interim, less carbon-intensive concrete will help.

      • Does it cut carbon by 35% or does the AI say it cuts carbon by 35%?

        They replace about a third of the cement with fly ash.

        So, yes, that reduces carbon since it uses less cement.

        The fly ash comes from burning pulverized coal, so this technique won't work after coal is phased out.

        No. AI of this variant is statistics with is a small part of Math and one that basically has no connection to concrete mixes.

    • Nothing lazy about it.
      Bayesian optimization is good way to find better ways to do things if you have enough data to train a sound surrogate model.
      The alternative is a physical simulation which may require supercomputers to do reasonably.

        What's better, 0% less of 200% bigger, or 35% less of 200% bigger?

        You wouldn't think this would be a difficult math problem.
    • Assuming they can actually pull it off and it's not some kind of concrete limited to this particular data center, it seems like it lowers carbon by 35% for everyone else that can use it as well. I'm guessing that whatever they're doing isn't as economical as regular concrete or someone else would have already done this. Even if you don't give a single damn about the environment the amount of money to be made from green initiatives is staggering and this seems exactly like the sort of thing that could get a

      • Disclaimer - I'm not a concrete expert. But I do know that there are many varying grades and mixes of concretes depending on application. Sure, this may not be a fix for all concrete applications, but then no concrete formula is. That doesn't mean that lessons from this application can't be applied to others.

      You and the AI are both wrong.

      • No. They're both more educated than you.

        *crete is not a set of synonyms made from different things.
        They have a set of requirements, neither of which are met by the poor structural strength of limecrete and hempcrete.

    Too bad using the AI was a non-green solution to a green problem. How many times over will the AI in that datacenter burn though the savings that the concrete created, in a day?

    What is the win from ditching the AI completely? You won't even need that datacenter, talk about going green.

    • Worse that its solution is wrong, and therefore a total waste of resources.
      Hempcrete and Limecrete are carbon negative ... ie waaaay better than 35% and these products are already commercially available.

        Limecrete has a maximum compressive strength of around 2500PSI, but is typically lower than that. (Hempcrete is MUCH lower than that, around 500PSI) Limecrete may be suitable for things Sidewalks, Patios, or Residential floors, but it's not even close to strong enough for structural use (4000PSI-ish) or even something like a garage floor. Hempcrete is only good for insulation.
    • It's not known how green the use of the "AI" was.
      It was a surrogate model for a physical simulation- far cheaper in energy terms than a traditional physical simulation.
      Whether or not that was all cheaper than just using traditional concrete is a quite simple "Yes."
      Cooking limestone into calcium oxide emits 1 CO2 molecule per calcium oxide molecule. It's a fuck-ton.

      You've commented multiple times about hempcrete in this story, while completely disregarding that (according to your own Wiki link) it is not fit for purpose, as it's not load-bearing. The majority of concrete in any build is in the slab, which is load-bearing by definition.

    • The AI didn't invent something ...

      What I'd like is some clever additive... such as carbonated water makes it better and greener concrete... and how it could be used for structural footings then a way to fill the rest with limecrete and foam blocks.

      • The Bayesian Optimization (including it model) zeroed in on a concrete with their basic requirements after being trained with the knowledge of existing concretes.
        Since we seem to be calling this particular Bayesian Optimizer "AI" (fine by me), the AI did, indeed, invent it.

    • During WW2, the Japanese mixed coconut fiber into concrete to make bunkers.

      The fibers reduced the amount of cement needed, and made the concrete more flexible so it was resilient to shelling.

      Jesus dude. Are you getting paid by "Big Hempcrete" to post this or something? Five comments with the exact same (under-informed) point?
  • This just confirmes that AI is going to save the world.

    • Unfortunately not

      Hempcrete exists and is carbon NEGATIVE.

      That the AI didnt suggest this proves your assertion that AI is going to save us is wholly incorrect

      In all honesty though that the AI didnt suggest either Hempcrete or Limecrete which are commercially available and CO2 negative tells us either that the AI is unfit for purpose or for some reason these products were deliberately excluded. It tells us that those who enlisted the services of the AI have been promoted to a high level of incompetence.

  • I thought Meta had its own AI, given all the data its slurped up you would have thought they would dog food instead of farm out.
  • If they are simply reducing the strength to just barely meet the engineering requirements, that's a slippery slope. We aren't back in the days where everything was overbuilt. We are in the 'will it last through tomorrow and the check clears' days of construction.

    If they are increasing aggregate size to reduce the refined parts of the mix, that's also cause for concern.

    And if this new mix is kept as a trade secret, why are they hoarding information that could help save the world?
