Photonic Computer - a "supercharged GPU" with very low energy consumption

Yes, we all wish for Quantum Computers... but in the meantime we need something here and now!  Could Photonic Computers fit that role? Just about everyone has heard of fiber optics – using light for data transmission – but did you know that light can also be used for computing? There's a new commercial product expected for early next year (2022) . I contacted the CEO, Nicholas Harris, of a 4-y.o. startup, Lightmatter , interviewed in April 2021 here . Photonic computers, at least in their first commercial appearance, are essentially accelerator cards for Linear Algebra - and so of special interest for Machine Learning and some types of simulations.    Their claims are remarkable: 10X faster than some of the best GPUs using 90% less energy can be used with existing software stacks, such as TensorFlow commercially available early next year (2022) a lot of future growth, as additional wavelengths of light get used in parallel My own interest is pr
