I recently was talking to a Professor of Computer Science at Oxford, who had contributed to a multi-disciplinary discussion paper which discussed AI and creativity (mostly in the context of intellectual property law, as the lead contributor (of about 10 academics) was an IP partner from the San Francisco office of a law firm who was an academic visitor on sabbatical). One of the themes addressed was the strong evidence that human creativity diminishes noticeably and rapidly when humans use AI to supplement creative endeavour. Original thought diminishes and works tend to a mean.
I don't think that sounds like what we want from GCA?
