  1. Great video! It really makes me think that normal CPUs would need a couple of analog matrix multiplication units where loading the matrix constants would be a slow operation but computing output for a big array of input would be fast. Because normal CPUs already run fully digital otherwise, it would make sense to return to fully digital domain after each such analog operation. In addition, the variable resistors wouldn't need to be accurate but only stable – you could compute calibration values for each resistor by inputting known input arrays with known output values and compute the suitable calibration values (basically input identity matrix multiple time with rows and columns mixed for each retry).
