How AI text watermarking works: a visual guide

Although this looks like a clever approach, a kind of stochastic key, I do not see how this guarantees to distinguish text written by big babble machines versus humans. Humans also have a certain pattern of writing, a given distribution of how some words are more likely to appear than others. How can one tell them really apart?

As an indicator, yeah, might be usable. But I wouldn’t read too much into it before seeing results of a study that runs actual tests.
