Often imitated never equaled. Abstract expressionism was, and often remains, a high-brow art con game. That much is obvious. But many critics who were otherwise unimpressed by the 'abstract movement' felt that its founder, Pollock himself, was on to something different. They could see that he was seeing.... something. Pollock himself always maintained that he was painting "The rhythms of nature". Recently a discovery was made about his work that lends a lot of credence to his vision. I saw the documentary elsewhere, but this quote from the Wikipedia article on Pollock. tells the story better than I can.
In the 21st century, the physicists Richard Taylor, Micolich and Jonas studied Pollock's works and technique. They determined that some works display the properties of mathematical fractals. They assert that the works expressed more fractal qualities as Pollock progressed in his career. The authors speculate that Pollock may have had an intuition of the nature of chaotic motion, and tried to express mathematical chaos, more than ten years before "Chaos Theory" was proposed. Their work was used in trying to evaluate the authenticity of some works that were represented as Pollock's.
As for this article... I bought a painting at IKEA for an apartment we were renting out . It was an abstract print on canvas, but it had real paint on it with lots of texture. I wondered if it was painted by a robot or some kind of 3-D process since it was one of several. Interior designers like abstracts because they are non-entities. They fill space but disappear. Since they have no narrative they can't offend. That is, unless you are offended by the very idea of them.
