Other than that the author wont survive one minute in China (I doubts they are interested to visit anyway), a lot of the reasons/rationales seem pretty weak. I also hate QR codes as menus, but not because printing a menu is easy, it is the human interaction that suffers. I can spend days without communicating with humans here… which is quite distopic. Although enjoyable every now and then (after a 80 hour work week for example…)
