Minimum viability is non-compatible with complexity.
We can use it as a threshold milestone but not as a moment of generalization. Complexity design differs from linear system thinking and cybernetics in its meta adaptability: adjusting feedback mechanisms.
Minimum viability is the minimum thinking needed to produce some pseudo-generalization that can scale to all instances.
The delta between that generalization and the natural world (actual or possible) is where creativity can seek and work with complexity.
I never correlated minimum viability with simplicity (nor elegance). Both feels in conversation with complexity for me, by the way.
To me, there are two "simples". The first is simple because you don't know any better. The other is simple because you are so proficient that it's elegant. I think an elegant system might incorporate complex thinking and also minimum viability, like in Picass's minimalist series on the bull.
