There are two theories for the source of ideas. The first one views them as a kind of manufactured product and the human brain, each with its own unique experiences and inherited traits, as a factory. The second is that ideas are revealed, not produced; their actual source is on the other side, and we are just channels. Which is correct?
There is no definitive answer to this question, of course, but AI will be incapable of receiving revelations, so it should give us some additional insight into the matter as it develops over the years. In the meantime, given my experience communicating with the other side, you can count me among the ancient Greeks (the Muses) and the many past and contemporary artists who have embraced the channeling theory.
