No, we are not close to the limits of technology by a long shot. But we are closer to the limits of technology applying invisible (to most) and compounding negative impact to the world. All popular consumer-based technologies today deploy an attempted totalitarian monism steeped in absolutism, in blatant disregard to the relativity that encircles the world, including nation-state sovereignty and freedom to each his own.
The institutionalized socialism by the pageantry of populism on social media is already producing debilitating group-think, responsible for the dumbing-down of humanity and a systematic deafening to think and act different. All while exactly those meaningful differences are so pertinent to the strength of our evolution.
A similar grandiose and possibly more dangerous depravity of reason is on the horizon with the advent, adoption and mindless pageantry of Artificial Intelligence, induced by the make-believe that consequence interpreted by technology can be traced back to plausible cause. Ignorant to how mankind, without technology, still struggles to differentiate between consequence and cause.
So, the limits of technology are not constrained by its potential to change the world for the better, but the limits of technology are defined by its impending inability to locate an ever-lasting pageantry of “greater-fools” who remain ignorant to the inescapable rules of evolution, those dictating the best way how to change the world. Presuming of course man comes to the realization it must subjugate to nature, rather than attempt to control it. Not a foregone conclusion.
Technology must begin to walk a smarter line to reverse the damage its naive populism applies to mankind, one in which it begins to support and respect the plurality of freedom and differences that defines a brighter future for all of mankind.
