Yes it is. The scientific name is "diminishing returns". (And in physical life, if one overdoes it with laziness, they can get from obese to pressure ulcers)
Right, sure, but we're talking in a thread about a machine which folds your clothes for you, or a house with two dishwashers so you can use them straight from one and put them into the other afterwards. I'm not advocating lying in a La-Z-Boy wearing a VR headset, eating nothing but Cheetos and Mountain Dew for 6 days straight. I'm talking about dimming all the lights in the room when you put on a film, or having them…
Yes. And while that is nice to have, it's by no means as useful as "automatic clothes folding". A dimmer takes like 5 seconds to dim when you put on a movie -- whereas clothes folding takes up to tens of minutes.
