If realizing the true nature of mind is the ultimate goal that drives us to enlightenment, constant blizz and the end of suffering, what would be the interest of developing technology?
Technology makes life easier and helps us live longer, but why would this be of benefit if happiness comes from within ourselves regardless of the life conditions surrounding us?
To put the question within a context, imagine a different setting from that of today. Go back in the past to a point far away from the industrial evolution and the invention of complex machinery. Otherwise it wouldn't make sense if we ask the question within today's context given that we live in an era of great technological advancement. There is no interest on going back (or at least I think so).
Technology has driven many advances that have considerably improved our daily life, but at the same time it is technology that has driven a society of consumerism. Besides, technological development comes from people who are "thirsty" of knowledge, the main root of dukkha (one of those words difficult to translate, but that it is often translated as "suffering"). So the main root of technology may be also the main root of suffering.
This question arises from a personal thought: If the humanity had been composed of good Buddhists seeking enlightenment from the "beginning of intelligent human kind", we would still be living a simple life in the jungle and perfectly happy as happiness is within ourselves and should not be conditioned by the outer world. All of this without great technological advancements.
