I will caveat my first comment by also noting that I am well versed in computer music history, and read many many papers in CMJ[1] and elsewhere about generative and automatic composition tools such as Emily Howell[2]. I do NOT have a problem with generative, algorithmic and automatic composition in this sense, as an extension of the creative intentions of the human composer, in the right context. See also Autechre[3] for what can be done with Markov chains and good taste. What we are discussing here is the musical equivalent of a dishwasher.
Addendum: I would highly recommend the Margaret Boden book referenced in the wiki on David Cope/Emily Howell, which is an absolutely fascinating read and was incredibly far-sighted in its enquiries on this topic.
