Laundry folding is an instructive example. Machines have been capable of home-scale laundry folding for over a decade, with two companies Foldimate and Laundroid building functional prototypes. The challenge is making it cost-competitive in a world where most people don't even purchase a $10 folding board.
I would guess that most cooking and cleaning tasks are in basically the same space. You don't need fine motor control to clean a toilet bowl, but you've gotta figure out how to get people to buy the well-proven premisting technology before you'll be able to sell them a toilet-cleaning robot.
Counterexample: Everyone uses dishwashers. Yet I don’t think we’ll have a robot doing the dishes human-style, or even just filling up and clearing out a dishwasher, within the next decade or two, regardless of price.
Part of the tradeoff there is efficiency. I like my dishwasher because it's as good at getting things clean as I am but it does it using less water and less soap, and at scale, it takes less time too. It's just a great use case for machine automation because you can do clever stuff w/a dishwasher that's hard to replicate outside of that closed environment.
I struggle to imagine a scenario where a 1-2 person household would get the same benefits from something like a laundry-folding robot. I hate folding my laundry and I still can't imagine buying one since I simply don't do laundry that often. If I really wanted to spend less time doing laundry, I could spend the cost of that laundrybot on a larger collection of clothing to wear, for that matter.
Robot vacuums are a good comparison point since vacuuming is something you (ideally) do frequently that is time and labor intensive. I do own one of those, and if it got better at dealing with obstacles thanks to "AI" I would definitely like that.
I think it would have to be a general-purpose robot, and doing the laundry would just be one of many things it can do, similar to how running a particular program is only one of many things a computer can do. More than that, I believe it would actually require a general-purpose robot to handle all contingencies that can arise in doing laundry.
As someone who does laundry about twice a week, it would certainly be nice. But it’s a pie in the sky at this time even just on the technological side.
There's plenty of machines which are expensive, bulky, single purpose and yet commercially successful. The average American household has a kitchen range, refrigerator, dishwasher, laundry machine, dryer, television, furnace, and air conditioner. Automatic coffee machines and automatic vacuums are less universal but still have household penetration in the millions. I really think the household tasks with no widely available automation are simply the ones that nobody cares enough about doing to pay for automation.
A robot servant that does literally 100% of chores would be a game changer, and I expect we'll get there at some point, but it will probably have to be a one-shot from a consumer perspective. A clever research idea to reach 25% or 50% coverage still isn't going to lead to a commercially viable product.
