That is a very apropos reference. If you're familiar with Cubism, you know that there's Picasso, and then there's Braque. The one is an art celebrity beyond almost any other, and the other isn't.
But they developed Cubism in parallel. There were periods where their work was almost indistinguishable. "Houses at l'Estaque", the trope namer for Cubism thanks to the remarks of a critic, was in fact by Braque.
You can generate infinite recognizable Basquiat from an AI, but is it Basquiat? No, of course not, because Basquiat's style operates within the context of a specific individual human making a point about expectations and the interface between his race and his artistic boldness and audacity as experienced by his wealthy audience. Making an AI 'ape' (!) his art style is itself quite the artistic statement, but it's not the same thing in the slightest.
You can generate infinite Rothko as 512x512 squares, but if you don't understand how the gallery hangings work and their ability to fill your entire visual field with first carefully chosen color, and then a great deal of detail at the threshold of perception of distinctions between color shades meant to further drive home the reaction to the basic color's moods, what you generate is basically arbitrary and nothing. Rothko isn't 'just a random color', Rothko is about giving you a feeling through means that aren't normal or representational, and the unusualness of this (reasonably successful) effort is what gave the work its valuation.
Ownership of the experience by a particular artist isn't the point. Rothko isn't solely celebrity worship and speculation. Picasso isn't all of Cubism. Art is things other than property of particular artists.
What makes it awkward is the great ease by which AI can blindly and unhelpfully wear the mask of an artist, such as Basquiat, to the detriment of art. It's HOW you use the tools, and it's possible to abuse such tools.
