I’m not a fan of Extropic, but I’m seeing a lot of misconceptions here. They’re not building “a better rng”- they’re building a way to bake probabilistic models into hardware and then run inference on them using random fluctuations. Theoretically this means much faster inference for things like PGMs. See here for similar things: https://arxiv.org/abs/2108.09836 There’s a company called Normal Computing that did something similar: https://blog.normalcomputing.ai/posts/2023-11-09-thermodynam...
