Chicken and egg, perhaps? OOO lives and breathes state, so complexity (defined as an excess of state consideration) seems a natural pairing, yet the overhead and complexity is increased by each in response to the necessity of the other? That is, when complexity of the problem shifts, there is a parallel increase in the complexity of the OOO solution.

The general anxiety of the movement towards functional or procedural programming in general might also be a feature of age: a young programmer eager to impress that they can juggle 8 balls effortlessly, but called upon to do the same 15 years later might admit 3 balls sufficed to begin with, and is closer to an attainable sustainable solution.
