Abstract Expressionism evolved and ended in about 15 years. While the idea and approach could still be valid today, just duplicating a style without adding something to it or making it your own in some way is just a painting exercise.
I respect what the movement did, just as I respect Pop, Minimalism, Photorealism, Post-Modernism etc, but when the candle goes out on a movement, it can only be relit by taking it to the next level.
In my opinion, not many people are trying to do this. They just do what everyone else was doing, just a few decades later.
Art is a process, and you have to experiment to discover your own path. Sometimes it is learning from the past.
I hope to see a progression in some of the artists here, and wish them all the luck in there journey.
