We have hard-wired non-programmable computers in production today. GPUs have sub-components that do fixed-function computation and don’t run on instructions. I suspect this analog AI processor is not programmable: https://www.mythic-ai.com/product/m1076-analog-matrix-proces.... It seems likely to me that we’re about to see a lot of growth in specialized non-programmable hardware since chips have started hitting size & process limitations. Turning common workflows into fixed-function hardware is one of the lowest hanging fruits we have for increasing compute efficiency.

Plenty of DSPs can't be programmed. Many analog computers of old, as well.
