To completly replace artists, the model would need to fully understand speech and have a good model of the world. The failure cases of the monk and the negation show pretty clearly that the model does something more akin to a keyword search rather than actual NLP. This alone will be a major problem for the last 10% - the more complex edge cases you introduce, the closer you need to be to AGI to handle them. This might come at some point, but the effort needed will skyrocket for less and less payoff, so I think we can safely assume that this will still take some time.
