The main path going forward in improving Markov chains is expanding the individual "unit" that are selected by these chains. Current Markov chains only randomly select words to string together into semi-coherent thoughts, but what if they instead randomly select paragraphs, or even entire chapters? This will promote large-scale structure within the book, and ensure the plot will always be varied and engaging.
I hope that your grandchildren's Bachelor of Science would train them in curating brilliant works of art that can then be feed into the Markov chain and perform the one-dimensional random walk.
I was actually making fun of this way of producing "art" (such as music.) Obviously since the algorithm has no human 'state of mind' or emotion, it cannot include any in the art whatsoever. My comment was completely satirical.
My comment was satirical too actually. The whole idea of thinking computers have created something "new and original" just by shoving together bits and pieces of human-produced works of art seems somewhat ridiculous. It's not entirely ridiculous, as the computer did do some manual labor of piecing together the words, but ultimately, you are relying on a corpus of pre-existing work and then reassembling it together. Any emotion (or indeed, most of anything good) comes from the corpus, not from the bot analyzing and imitating the corpus.
