I could write an article about how, in order to buy something in a store, you're expected to queue up and present your chosen products to a human who picks them up and scans them - wow, "super creepy", right. An actual human running their hands over your stuff, glancing at your face and probably thinking about who you are, and why you're buying these particular products. The human might even get a look at your bank card. "What a bunch of weird nonsense" is the idea that is probably going through your head (see how I lazily assume you think like me, the article author).
