They’ve tackled part of the process. You still need to clear the table yourself, get rid of the large solid food scraps and saturated fats, load/empty the dishwasher. You then have things that need scrubbing, or material that can’t handle heat well, and those need to be cleaned manually.

I have a dishwasher, but find that I rarely use it because the time it saves is negligible compared to manual washing. The only time it’s helpful is after something like a dinner party where there are a lot more dishes than usual so space is the limiting factor.
