every cupboard in your house is a dishwasher. The dishwashers are smart, and if they have been opened, they know there might now be something dirty in them, so they will wash overnight that night. It's wasteful of energy because you'll be washing 99 clean plates and one dirty plate, but I think it would lead to a good user experience.
For commercial customers, absolutely. I first came across services like this a long time ago in Hong Kong[1] but it's pretty widespread in mainland China, Taiwan, and parts of SEA[2] because local restaurants tend to be quite small. Sometimes you can tell because you'll get your dishes as sets in sealed plastic[3] wrappers.

2. I've never personally seen it in Japan or South Korea, but I'm sure it exists.

Instead of every cabinet being its own dishwasher, you could have a wall-mounted dishwasher that automatically distributes clean dishes back to the cabinets.
Maybe this will be my retired-and-bored passion project later in life.
