That's definitely a strawman or just a straight up misrepresentation of what cookie clicker is. You only actually "manually click a picture of a cookie" for about one to five minutes, then you basically never click it again. It's described as an idle game where you play by not playing, and the core mechanic is "number get bigger faster". The game described in this thread is mindlessly clicking a button, no depth, no automation or acceleration. Just click a billion times to win.
