Almost certainly false.
> I also predict machine learning will never be able to surpass humans in terms of creative ability
Algorithms are already churning out papers that are accepted to journals, and they can compose crude music. This a mere 10-15 years after the study first began. I give it maybe 20 years before a computer generated song will appear on one of the top charts. These will likely still be domain specific algorithms.
> Humans can invent new things, machines seem only capable of rehashing existing things
So you think human brains run on magical pixie dust? "Things" that humans invent can all be described by finite bit strings, which means generating "new things" is a fiction.
We discover these compositions just like a computer would. The secret sauce that we have but don't yet know how to describe algorithmically, is discerning those bit strings that have more value to us than others, like a clever turn of phrase is more valued than a dry, factual delivery.
> If you "teach" a machine how to write by feeding it thousands of books, but you exclude books that have unreliable narrators, will the machine ever write a book whose narrator is unreliable? I think not.
I don't see why not, even if we stick to domain-specific novel generation, but it depends on how you train the system based on the inputs. Random evolution is hardly a new concept in this domain.
