You just described most things in life.

You are saying that your disinterest in these works is justified because the artist claimed to create them without conscious thought during the process?

I happen to like these works, and I was actually happy when my own generative art attempts resulted in output similar to these (but lacking the texture and subtle complexities these appear to have).

Improvisational jazz is sometimes made with no conscious plan or thought during the process, but it is built upon structures and foundations which were very conscious efforts in the education of the musician. I don't see why the same cannot apply to visual art.
