Reddit reviews The Official Patient's Sourcebook on Acne Rosacea: A Revised and Updated Directory for the Internet Age

From a programming perspective the examples are completely different from writing a cohesive novel, and so don't really count as proof of concept.

• Number 1, Number 4, and Number 6 are probably not much more than fancy mad-libs or decision trees at their core.
  
• Number 3 wasn't even fully computer generated. The computer generated aspect was probably done with a Markov Chain or similar, which just spits out words based on the probability they appear after other words in English text-- there's no overarching context or understanding.
  
• Number 8 looks a little impressive on the surface, but was definitely helped by a human at least a little. Hard to say more without sitting through a long video; but it's hard to take someone who generates deliberately misleading spam books for amazon too seriously.
  
  Apart from #8 what's missing in all these? Memory. Understanding. Cause and effect. Unique and purposeful meaning. Anything that actually would actually make a novel enjoyable and not just a meaningless insane stream of consiousness.
  
  It's easy to spew out words with statistics or sentence fragments or fill in the blanks. It's quite another thing to keep track of the implications of a mistake that a character made three chapters ago and write about it sensibly.
  
  With all the advances nowadays it wouldn't be too surprising if we actually got computer intelligence eventually, but that will be at most only distantly related to these mad-libs and meaningless superficial poems.
