The fact that this has been replicated is amazing!

    Stupid question probably - is computing power what is holding back general AI? I’ve not heard that.

      What’s holding back AGI is a complete lack of progress toward anything like intelligence. What we have now isn’t intelligent, it’s multi-variable probability.

        It’s not that it’s not intelligent, it’s that predictive language models are obviously just one piece of the puzzle, and we’re going to need all the pieces to get to AGI. It’s looking incredibly doable if we figured out how to make something that’s dumb but sounds smarter than most of us already. We just need to connect it to other models that handle other things better.

          The biggest hurdle is that we don’t actually know what intelligence really is at all yet, computationally. Most of the history of science has been repeatedly learning “but things were actually more complicated than originally expected,” so making claims that we’re soon to be able to replicate something that we don’t actually properly understand yet may be a bit premature. The desire to replicate human intelligence by a machine has been around since at least the 1200’s brazen heads, and yet for everything we’ve discovered since we’re still just beating our heads against a wall trying to sleuth out what it really is that makes us ‘think.’

        There is still heat generated by the act of computation itself, unless you use something like reversible computing but I don’t believe there’s any current way to do that.

        And even then, superconducting semiconductors are still going to be some ways off. We could have superconductors for the next decade in power transmission and still have virtually no changes to processesors. I don’t doubt that we will eventually do something close to what you describe, but I’d say it’s easily a long way off still. We’ll probably only be seeing cheaper versions of things that already use superconductors, like MRI machines.

            I appreciate you revising your reply to be less harsh, I wasn’t aiming to correct you on anything I was just offering some thoughts, I find this stuff interesting and like to chat about it. I’m sorry if I made your day worse, I hope things improve.

            I said superconducting semiconductors as just a handy wavy way to refer to logic gates/transistors in general. I’m aware that those terms are mutually exclusive, but thats on me, I should have quoted to indicate it as a loose analogy or something.

            The only thing I disagree with is your assessment that computation doesn’t create heat, it does. Albeit an entirely negligble amount, due to the fact that traditional computation involves deleting information, which necessarily causes an increase in entropy, heat is created. It’s called Landauer’s principle. It’s an extremely small proportion compared to resistive loss and the like, but it’s there none the less. You could pretty much deal with it by just absorbing the heat into a housing or something. We can of course, design architectures that don’t delete information but I’m reasonably confident we don’t have anything ready to go.

            All I really meant to say is that while we can theoretically create superconducting classical computers, a room temperature superconductor would mostly still be used to replace current superconductors, removing the need for liquid helium or nitrogen cooling. Computing will take a long time to sort out, there’s a fair bit of ground to make up yet.

                I think “rounding error” is probably the closest term I can think of. A quick back of the envelope estimation says erasing 1 byte at 1GHz will increase an average silicon wafer 1K° in ~10 years, that’s hilariously lower than I’m used to these things turning out to be, but I’m normally doing relativistic stuff so it’s not really fair to assume they’ll be even remotely similar.

        Really appreciate the write up! I didn’t know the computing power required!

        Another stupid question (if you don’t mind) - adding superconductors to GPUs doesn’t really se like it would make a huge difference on the heat generation. Sure, some of the heat generated is through trace resistance, but the overwhelming majority is the switching losses of the transistors which will not be effected by superconductor technology. Are we assuming these superconductors will be able to replace semiconductors too? Where are these CPU/GPU efficiencies coming from?

            Semiconductors are used for transistors because they give us the ability to electrically control whether they conduct or resist electrical current. I don’t know what mechanism you’d use to do that with superconductors. I agree you don’t ‘have’ to have resistance in order to achieve this functionality, but at this time semiconductors or mechanical relays are the only ways we have to do that. My focus is not in semiconductor / IC design either so I may by way off base, but I don’t know of a mechanism that would allow superconductors to function as transistors (or “electrically controlled electrical connections”), but I really hope I’m wrong!

      Simply throwing computing power at the existing models won’t get us general AI. It will let us develop bigger and more complex models, but there’s no guarantee that’ll get us closer to the real thing.
