@zero this guy doesn't understand the technology. Tensors are basically the data you need to map a higher-dimensional landscape to a lower one, or vice-versa. The data in a tensor allows you to make a transform. Transforms are SLOW AS BALLS on transistors. You can perform a transform in an optical accumulator almost instantly (nyquist rate of signal) by combining multiple analog signals that represent vectors and just sampling the result. The instant someone puts out a photonic tensor processing unit all this technology will be blown away in a matter of hours
