For me doing the dishes is a 10-15 minute chore in the sink with some hot water but most people don't seem to object that their dishwasher takes 3 hours to do the same job with superheated steam or whatever. It still saves them the 15 minutes.
Don't forget that the dishwasher also uses less water and the dishes get sterilized by the steam.These features may or may not be important for a particular user.
