That still requires gathering the dirty items together, loading/unloading, keeping track of when it is full/time to run. People saying this mean they want a robot like Rosie from the Jetsons to take care of that sort of housekeeping, not for a machine that makes the task easier to do themself.
Edit: to be clear, I don’t think a washer machine or dishwasher is a hassle and problem that needs solving, but that doesn’t take away from the message of “AI should help make life easier, not replace the creative outlets additional free time should allow”
I agree, and those “problems” will never be fixed by AI. Not everyone who laments that AI should make life easier is a supporter of AI, though. Sometimes it’s a general “[technological] advancement should be for the good of the people, not the good of the select shareholders”.
