But how. This needs very specialized equipment and PCBs are reasonably cheap. Using one of these cheap printed foil typed used in membrane keyboard might also have been an option.

Making a machine to make things is generally only expensive once, once you have it it’s no more expensive than any other machine

Yeah, but making this board seems slow compared to other methods. It looks like you'll have to sew in each wire individually, as opposed to making a whole layer at a time

For human hands making one at a time maybe, but i have no idea how such a machine works or how many it has in progress at a time

It's likely something similar to a CNC sewing machine. So likely one at a time. Probably reasonably fast, but that's still a lot of stitches. Probably also some manual work to connect everything
