Paper bags allow people to transport various things in a single place, they don't have to depend on their hands only. It's a very useful invention.

Dishwasher · Josephine Cochrane
Dishwashers make the task of cleaning the plates, the spoons, etc. easier. We don't need it a 100%, but it's an opportunity to get everything cleaned without any effort.
