I'm sort of in two minds about it. Most abstract art that I see fails to do anything at all for me, but I like the abstraction-like patterns we find in the world all around us, including the microscopic world:
All photographs, and thus, all 100% realistic, and all of them also kind of abstract. In the the case of the first, most people would not even know what it is, so if you made a photorealistic painting of it, people would think you're doing abstraction.
Whether something is abstract or not may depend on nothing more than how far you zoom in:
I find that when I do like an abstract piece, it is usually because it suggests something "real," or seems like it is abstraction that flowed from a study of the real world. Which is why, to StLukes's endless irritation, I rather like some of Georgia O'Keeffe's abstractions.
Exercise: go make a drawing or painting of the above two "abstract" pieces and show them to people; see what kind of reactions you get. I'm too lazy to do it myself, so I'm waiting for someone else to go try it.
On the other hand, I'm going through one of my periodic manias for botanical art, which I like partly precisely because of its abstraction-like aspect, so maybe I'll make a whole career of this sort of "realistic abstraction." I'll let you all know when I win the ARC's salon competition.
