There is a difference between inherent complexity and manufactured complexity.

Inherent complexity can only be moved around, but even then you still want to move it to a place that can handle it properly. If the best you can do is a complex decision tree then it should at least be well-audited and well-documented instead of having a dozen separate buggy ones that all give different results for unknown reasons.

But much of today's complexity isn't inherent. It's manufactured. It's just not required to be there at all and there is much to be gained by taking it out.
