Any clues to how they plan to invest $500 billion dollars? What infrastructure are they planning that will cost that much?
I'll make a wild guess that they will be building data centers and maybe robotic labs. They are starting with 100B of committed by mostly Softbank, but probably not transacted yet, money. > building new AI infrastructure for OpenAI in the United States The carrot is probably something like - we will build enough compute to make a supper intelligence that will solve all the problems, ???, profit.
Thermodynamic neural networks may also basically turn everything on its ear, especially if we figure out how to scale them like NAND flash.
If anything, I would estimate that this is a space-race type effort to “win” the AI “wars”. In the short term, it might work. In the long term, it’s probably going to result in a massive glut in accelerated data center capacity.
The trend of technology is towards doing better than natural processes, not doing it 100000x less efficiently. I don’t think AI will be an exception.
If we look at what is -theoretically- possible using thermodynamic wells, with current model architectures, for instance, we could (theoretically) make a network that applies 1t parameters in something like 1cm2. It would use about 20watts, back of the napkin, and be able to generate a few thousand T/S.
Operational thermodynamic wells have already been demonstrated en silica. There are scaling challenges, cooling requirements, etc but AFAIK no theoretical roadblocks to scaling.
Obviously, the theoretical doesn’t translate to results, but it does correlate strongly with the trend.
So the real question is, what can we build that can only be done if there are hundreds of millions of NVIDIA GPUs sitting around idle in ten years? Or alternatively, if those systems are depreciated and available on secondary markets?
What does that look like?
