Waiting for a dishwasher to do 3+ hours of washing while leaving food bits at the bottom of the machine only to become smelly overtime is ridiculous.
You're absolutely right appliance companies won't be hiring anyone who thinks like me and Jerome when people want quiet, capacity, sleek new looks, gliding racks, cleaning, drying, soil handling, reliability, durability, longevity and serviceability in roughly that order.
A machine that can clean in circles in less than an hour will never be seen as a serious contender in the eyes of the public when it can be heard running or can't fit the whole china cabinet.
