> The reason that these switches and dials are ok to be hardcoded in metal and glass is that they (and the people) do the same thing, over and over, year after year, for decades at a time. Rinse and repeat. The keys on my keyboard and mouse have been hardcoded into metal and plastic since I started programming. Likewise the frets of guitars I've played since boyhood. That does not mean I've been doing the same thing over and over for decades at a time, rinse and repeat. Or maybe it does.
