If you go for a full curve over the space, then yes.
But like NAND, there is room for, I don’t know what to call it, “quantization”? You get a few values out instead of just binary.
My guess is, like other issues of precision, errors can get out of hand if you are not careful.
But being an EE in another life, I can tell you the power waste and slowness of ALUs is kinda wild.
I definitely believe that Gaming on CPUs is like ML on GPUs. Slow, and waiting for something more appropriate to come along.
Don’t know if these guys are the ones to do it (and they are, ahem, not alone). But someone will deliver 100x to 1000x boost either in speed, power efficiency, or both.
