  • Study claims to provide first direct evidence of dark matter

    Jump

  • I am a physicist, studying dark matter.

    Firstly, It would be nearly impossible to prove that dark matter definitely does not exist.

    And secondly, there are no alternatives to dark matter that come even close to explain our universe as successfully as dark matter.

    That doesn't mean it's right, but any explanation without dark matter is not favored IMO.

  • Alternatively, if you can't remove the modem, find and remove the antenna. And if you can't remove the antenna try and surround it with a metal, like aluminum foil.

  • Well I'm probably wrong then, framework said they couldn't get good performance and maintain signal integrity with upgradable memory for the Ryzen Max cpus, so this is likely discrete Cpu and GPU. Probably all soldered in the same mainboard though.

  • This seems to blur the lines between desktop and mobile APU's, but I would bet that's it's closer to a higher clocked mobile chip, than it is to desktop. The only reason I think this is the case is due to the similarity spec wise with the Max 385, and that it's semi-custom.

    If it was just a 7600x CPU + 7600 GPU I think they would have just said so. It could be separate CPU+GPU, but I think it might be possible that it is built more like a SOC, where the GPU is just given its own dedicated VRAM.

    Looking at the hardware of say a PS5, it has 16 GB of GDRR6, the same as the Steam Machine's VRAM.

    If everything is soldered anyway, there is no reason to have separate chips for CPU+GPU, especially if that hardware already exists like the AMD Ryzen AI Max line.

  • This thing has pretty interesting hardware:

    The chip almost looks like a cut down AMD Ryzen AI Max 385, but with fewer CPU cores and GPU CUs, but the GPU gets its own dedicated VRAM, rather than sharing it, like it does in something like a Framework Desktop.

    It also seems like it gets a decent amount of power, so likely at higher clock speeds, performance should be pretty good for not that much money. If this is supposed to be a console then it can't be much more than a PS5 at $550 or PS5 Pro at $750.

  • Investors are making up the highest share of homebuyers in 5 years

    Jump

  • Yes of course, but how do you propose we get that to happen?

    Why are these homes empty in the first place? Are they in the same places where housing is needed?

    And even if you could house all homeless people, that still leaves the problem of the crushing expense of housing in many places.

  • Investors are making up the highest share of homebuyers in 5 years

    Jump

  • That's kinda exactly my point? If someone could print a fuckton of new bitcoins it's value would drop. The same is true for housing. We may have technically enough housing for everyone, but that means nothing if that housing is not also where people want to or need to live.

  • Investors are making up the highest share of homebuyers in 5 years

    Jump

  • While these investors are absolutely soulless and deserve to be called out, there's another aspect of this problem that I feel doesn't get talked about enough.

    If we just built enough housing this problem would go away. And it would be easy if we had a system that allowed people to build new things and undercut competition. But we can't because regulations make it nearly impossible to make anything other than houses.

    People investing on houses are a symptom of the larger overall problem, of there not being enough fucking housing.

  • Will CEOs eventually have to replace themselves with AI to please shareholders?

    Jump

  • At its face value, base elements are not enormously complicated. But we can't even properly model any element other than hydrogen, it's all approximations because quantum mechanics is so complicated. And then there's molecules, that are even more hopelessly complicated, and we haven't even gotten to proteins! By comparison our best transistors look like toys.

  • I did not immediately dismiss LLM, my thoughts come from experience, observing the pace of improvement, and investigating how and why LLMs work.

    They do not think, they simply execute an algorithm. Yeah that algorithm is exceedingly large and complicated, but there's still no thought, there's no learning outside of training. Unlike humans who are always learning, even if they don't look like it, and our brains are constantly rewiring themselves, LLMs don't.

    I'm certain in the future we will get true AI, but it's not here yet.

  • Will CEOs eventually have to replace themselves with AI to please shareholders?

    Jump

  • Yeah a lot of it is messy, but they are not being replicated by commodity gpus.

    LLMs have no intelligence. They are just exceedingly well at language, which has a lot of human knowledge in it. Just read claudes system prompt and tell me it's still smart, when it needs to be told 4 separate times to avoid copyright.

  • Will CEOs eventually have to replace themselves with AI to please shareholders?

    Jump

  • Current Ai has no shot of being as smart as humans, it's simply not sophisticated enough.

    And that's not to say that current llms aren't impressive, they are, but the human brain is just on a whole different level.

    And just to think about on a base level, LLM inference can run off a few gpus, roughly order of 100 billion transistors. That's roughly on par with the number of neurons, but each neuron has an average of 10,000 connections, that are capable of or rewiring themselves to new neurons.

    And there are so many distinct types of neurons, with over 10,000 unique proteins.

    On top of there over a hundred neurotransmitters, and we're not even sure we've identified them all.

    And all of that is still connected to a system that integrates all of our senses, while current AI is pure text, with separate parts bolted onto it for other things.
