Right now not many people have enough calculation power available to really experiment much with AI. I'm only working with game AI where the bots run around in a simplified model world with a simplified set of available actions. But even with those constrains the by far biggest challenge is is the available processing time. You still have to pre-calculate much stuff that people can work out in a second. The current state of AI feels to me similar to the state the 3D graphics felt to me in Amiga times. You can already do a few nice effects in real-time, but for real cool stuff you still have to run the computer 3 days. The basics are already mostly there even if they might be used in new compositions in 20 years.
