1. I agree with you that AI of today is not as good as a pig brain. However, it is not strong coupling that blocks the way of a pig-level AI. It's something deeper and harder.

2. Modern reductionism, differing substantially from ancient trivial reductionism, is called "synthetic reductionism" which can deal with, and are dealing with, strong coupling cases everyday. Many people of the 21st century still stuff their heads with the cultural junk of the 18th century.That may be not their fault, but lecturing others to take such 'traditional lotions' is rather a sin.

3. What do you mean by "这种方法对于强耦合的情况就不灵了" and "用夸克来解释强子就不灵了"? Superconductivity and QCD, both being a theory for strong coupled systems, are great examples of modern reductionism.
