They've used a lot of signifiers of Expensive Vintage Art with a Modern Twist - dark backgrounds, exaggerated flesh tones, rich-looking clothing, aggressive modern distortions - to suggest value. But the neural networks that may (perhaps?) be being fooled are the ones inside the brains of buyers.
By the end of the year this art will be available as an instagram filter and/or from a web page. Which is why it will be worthless. Neither the software nor the imagery are special enough to survive that.
The real art - if that's the word - is in how this is being run as a startup and is trying to turn investor money into a hype train.
That's technically not disagreeing with the OP. And I do think that the first one will be highly valued, independent of the fact that it'll be available. Just like the Banksy Image that was shredded will be worth so much more now; any images from now on that pull this trick won't be as highly regarded as well.
Other than that I agree: AI art is so easy to produce that the sheer quantity will make it uninteresting for collectors.
But hey, people are free to waste their money if they like.
I tried to make an auto-Mondriaan machine once, and I gave up after a few days. It's one of the hardest things I've attempted. It's incredibly easy to splash some black lines and primary fills around, and unbelievably hard to get the proportions and density right.
Cheap parlor tricks have a long and glorious history in art, and sometimes become important works of art.
