The chess experts were wrong qualitatively. They were saying that the best play was about intuition and feel, that computational power would never replicate regardless of its scale. (Data on Star Trek always lost chess matches implausibly.) Turned out that brute force calculation thirty moves deep does in fact outperform anything a human can foresee.

The same thing happened for Go a couple decades later. And now it's happening for AI art. Enough computational power and a sufficiently well-trained neural network can indeed exceed anything a human can do.

AI has been roughly doubling in performance every year or two, for quite some time. We just never noticed when it went from 0.0001% to 0.0002% of human capability. This is the year that it doubles from 1% to 2%. And there's not a lot of doublings left until it shoots past 100%.
