I don't believe autonomous composition or algorithmic composition itself to be propaganda. Propaganda is the notion, rather, that the computers are doing the composing, that the computers themselves are creative, that we have realized artificial intelligence. In fact, there is not a clear agreement on what intelligence is. That is –as far as I know- the scientific description of reality.
The reality is that composers are human, that music is a social practice. Composers eat, speak, make love, have being. Computers are not [yet?] capable of this.
