@MartinEscardo @jonmsterling @jac Regarding energy cost, the best new approach to addressing that issue is probably Thermodynamic Computing. I think if the claims by the startup extropic.ai are true then that's the future.I'm thinking perhaps in the future there will be changes to hardware which will incorporate these new architectures specifically for AI, like we have a CPU, GPU and hopefully a "TSU" (Thermodynamic Sampling Unit) for probabilistic computing.
