Page "Infinite monkey theorem" Paragraph 56

More sophisticated methods are used in practice for natural language generation.

If instead of simply generating random characters one restricts the generator to a meaningful vocabulary and conservatively following grammar rules, like using a context-free grammar, then a random document generated this way can even fool some humans ( at least on a cursory reading ) as shown in the experiments with SCIgen, snarXiv, and the Postmodernism Generator.
