We kitties who live with humans find ourselves surrounded by machines. Some machines are for doing good, such as being part of the cat blogging community.
Other machines are pure evil. I do not recommend getting this close to one of these. They are unpredictable.
Then there are weird machines that pose as cat toys. My suggestion: if your human brings home a so-called cat toy that needs a switch to start working, stay away! Fortunately I have not seen this thing since we moved.
