Cool tech demo, not even close to a level quality I'd consider paying for
Think about all the hard work that traditionally goes into composing a single title. Artists will spend days, weeks and sometimes months trying to iterate on ideas. Writing, composing, demoing, tracking and recording, mixing, etc. Think about all of the expensive software and hardware that goes into this process (instruments, microphones, studios, DAWs, VSTs, etc). It's an expensive and difficult process, it's very manual, very sequential.
This could easily be used to speed up that iterative process. Just ask this software to generate 100 ideas for your next bridge, and iterate that way.
