We don't build robots because the "hard/boring part" for the human is often NOT the hard part for the robot.
Take the dishwasher, for example, loading it is very hard for a robot, but easy and quick for a human. Washing the dishes is boring for the human, but a robot gets a sort of sick and twisted pleasure from cycling that dirty water around for hours on end.
In fact, we've removed some labor-saving features of houses (laundry chutes went away decades ago, and only recently has "laundry on the bedroom floor" become somewhat standard) for "safety".
MAKE DUMBWAITERS GREAT AGAIN
> Washing the dishes is boring for the human
I feel like the only person in the world who doesn't mind doing dishes. When we lived in the city, I feel like most of my friends would rather have an in-unit dishwasher than in-unit laundry. For me, doing dishes feels almost meditative.
(But I do hate folding/putting away clothes.)
Doing dishes by hand takes only slightly longer than loading and unloading a dishwasher. Especially modern dishwashers which don't really dry the dishes so you have to hand dry at least some of them before putting them away.
That may be the case but the dishwasher uses less power and water then you do washing dishes.
It's also not like I'm lacking for dishes that need hand washing anyway either: very large sauce pans, pots and chopping boards aren't fitting in the dishwasher anyway.
Fire safety is real. Ever seen a burned out house with an untouched bedroom because the door was closed?
I'd love a dumbwaiter simply for a place to queue items "this needs to get put away downstairs (next time I am downstairs)" etc. Instead I just use the shelf next to the stairs. Which doesn't work if I'm already carrying something to bring up/down stairs, and that pattern makes it so I'm likely to forget even when my hands are free.
I built a cart/track system that went from the basement to the outside via the bulkhead. It fulfilled that work pattern in some regards, but it also made it hard to use those stairs manually [0] so it also impeded getting things done. The design that kept the cart level used up way too much of the vertical space. The next version of this idea will be aimed chiefly at heavy things (with the commensurate work to tie down etc), and go through two transitions horizontal-sloped-horizontal,
[0] and yes blocking an exit is fire hazard I know I know
