i’d imagine the company would make 2, 4, 6, 10 drink dispensing machines… having commodity hardware makes it super cheap to just have different shells and a power bus that you bolt electronics and mechanics onto in discrete parts

heck each individual controller could read an RFID tag embedded in the syrup and update its display automatically just from the inserted cartridge

adding all the sensors for each, a display out for each… it’s really just way simpler to duplicate the hardware… honestly, good engineering
