Basic Pr opositions(Zittr ain, p. 64) The IT ecosystem functions best with generative technology at its core. Generativity instigates a pattern both within and beyond the technological layers of the IT ecosystem. Proponents of generative IT systems ignore the drawbacks attendant to generativity’s success at their peril.
