The article (and the embedded NYT video) seem to imply that WeChat is not just a dominant app, but is pretty much the only way to do things in China. For example the quote, "try and pay with cash for lunch, and you’ll look like a luddite."

So, what if you cannot use WeChat? Or if you're banned by their AI (which happens all the time with western apps)? Or if you simply choose not to? There must be other ways to book rides, hire services, pay people, chat, E-mail, and so on.. I (in the West) opt out of using Facebook+all FB properties, Twitter, Google, and so on, and I still have the full ability to live as a normal person. Surely China has cash and the ability to book things over the phone...?
