Typewriter/printing presses are for faster propagation or execution. AI in the cultural sense is about replication, hence the Artificial Intelligence tag. Typewriters aren't attempting to replicate or substitute, they are tools like a hammer. They are designed to be operated by humans since they are analog in nature, like your keyboard. AI doesn't need a keyboard, it's operating off our end contributions directly. It cares about the final, digitized form of the novels we feed it, no how we made it or came up with it.
That is the key difference here. It is the same thing when someone creates something based on their own direct experiences versus someone who is simply copying something. It is why AI art for example is increasingly looking bizarre in my opinion: it's completely recycled/fake.
