Metaphorically speaking, a dinosaur is any entity lacking the capacity to adapt to environmental changes in a timely fashion. While a dinosaur may well possess the ability to adapt it may be an unfortunate accident of biology or culture that predisposes it to an internal rate of transformative change that is relatively static compared to the rate of change in the environmental factors that, normally, support and optimize conditions for its survival. This inability to match the pace of change places the dinosaur at a competitive disadvantage that eventually pushes it to the margins of relevance and results in its eventual extinction—both literal and metaphorical.
No creature would invite change for its own sake and—humans being like most other creatures—expend enormous amounts of energy attempting to stabilize our situation and achieve a form of stasis that allows us not only to survive but to thrive in relative safety and comfort. We tend towards mitigating the effects of the unknown and the unpredictable and this requires apprehending and utilizing knowledge of the environment in order that we might exploit it to advantage.
Our ability to utilize binding symbolic language and symbolic artefacts and to fashion tools that—according to Marshall McLuhan—extend, enhance and accelerate our effective selves, creates a buffer between us and a natural order that challenges us with the timeless struggle for survival.
The fact that we will soon be uneasily celebrating the turnover of our biological counter to the 7 billion mark is a testimony to how successful we have been at disconnecting from or minimizing the risks that the natural order presents. One could argue that this disconnection could be better characterized as a complete domination and subjugation of the environment that carries with it a dire corollary for our long-term survival and that the technocomplex that we created constitutes its own environment with its own evolutionary pressures.
