The way I see it, there will always be something that takes us (the users) to the next level. Maybe you have all the racks and detergents, then you discover the dishwasher. Maybe some day we'll get an oven+fridge all in one. It might be hard to think about it but there is definitely room for growth. It might not be growing upwards, it might be sideways, or even abstract it to a different dimension.
