Specialization is a necessary part of the dynamic cycle.

To use Stephen Jay Gould's Punctuated Equilibrium as a frame of reference, in the equilibrium stage, the stable state the dynamic selects for specialization and complexity, as every resource is use and niche filled, but then the punctuation/unsettled stage selects for adaptability and resilience.

you have to read the cycle and not only not keep all your eggs in one basket, but know how to connect them. Be a generalist.
