Every system gets so good at what it does that it destroys itself.
In getting ever more optimized, it hollows itself out and makes itself brittle and unable to adapt.
Noise and variance is in tension with efficiency.
The ability to adapt comes from the noise and variance in the system.
You need noise to select over to adapt; the magnitude of noise you have in your system to select over sets your maximum adaptation rate.
Innovation and adaptation are a biased selection process over noise.
The system gets so good at one thing that it can't do anything else.
When the context changes (and the context, over long enough time horizons, always changes), it can't adapt, and it dies.
