Basically, they make humans' life a lot easier. But, it also uses electricity, which does not help humans. The pollution from the washing machines' electricity makes humans' life harder.

Ergonomics is the science concerned with designing safe and comfortable machines for humans.
Robots are the machines doing the work formerly done by Humans
ramps themselves, simple machines such as levers, the "A"-frame and thousands of slaves
Plastic molding machines; soldering machines; computer machines; humans; assembly machines; cooling machines; heating machines; electric machines; labeling machines; laser machines; conveyor machines.... etc.
yes,we have allowed machines to become our masters.
Humans are fundamentally different entities from machines. While machines are designed to perform specific tasks based on programming, humans have consciousness, emotions, and the ability to make choices that go beyond programmed responses.
