From this article I see them referencing that there is joy in creating and recognizing new patterns, which I agree with and makes some logical sense. But "abstractions" by itself is very different, which can be just a representation of one thing in another medium, and which doesn't logically generate pleasure.

The words "abstraction" or "abstract," also, according to my search function, don't appear on that page. Given that these can be unclear topics, we sometimes have to take care with our words.
