Despite his error regarding an ultra-intelligent machine being built in the 20th century (which did not happen -- even 21st century supercomputer is not an ultra-intelligent machine), this is an intriguing collection of ideas. This projection reality is still possible, despite this essay having been written by Vinge back in the 90's. Not much has changed since then.
Since the 2010's or even late 2000's, there have been rising factions of politics that are anti-intellectual and anti-fact, particularly when it does not serve the status quo. That has always been the case for politics, but the advent of the internet has internationalized this much further. This is the main reason why we have hooligans among athletes and even academics, as well as journalists. Because of this, we now have the vision of George Orwell attempting to cement itself as our present.
Vinge is right, as a part in the essay, I believe he meant that politics can obstruct innovation and progress. We can see this every day on various news outlets, even when we don't try our hardest to pay attention. Certain political realities possess the power to derail, or at the very least delay, this possible future, especially considering the rise of ultranationalist, nativist, authoritarian right-wing political leaders, who are almost always science-deniers and desire the return of the so-called Good Old Days, and the rise of the paranoid extreme of left-wing politics who, unlike the original progenitors of liberal thought (liberal, which at the time of the Renaissance and perhaps prior to the World Wars, was considered synonymous with scientific or reasonable), are unable to comprehend nuances and as a result outright demonize certain innovations (such as genetic engineering) that defy the norms, traditions and the common notions of what is natural and what is not, of what is human and what is not, and even deny their effectiveness in aiding the human condition and alleviating its suffering (such as vaccination, considering the spread of complacency in First World comfort, vaccines became poison to the uneducated). Many aspects of left-wing politics now demonize valid science in almost the same way that many aspects of right-wing politics demonizes science (although perversion of science has always been less of a partisan issue and more of a fear-of-war kind of issue).
However, behind all these realities, corporate influence can still provide the necessary influence for the development of the singularity. So perhaps, my concern with politics and the lack of education in society getting in the way of possible progress in technology and contributing instead to its dangers is rather moot. Maybe, the end sum will always lead to technological singularity. And I believe Vernon Vinge of 2017 would still agree, even if the statement comes from an oft-miseducated twenty-year old layman.
When it comes to the concept of transcending humanity, I truly think that other than a completely non-theistic interpretation of Buddhism (none of the Cambodian type), Nietzsche's, Schopenhauer's and Hegel's philosophies (or at least what basic understanding I have of their philosophies), the only other mechanism that one may use to distance oneself from the common spectrum of Good and Evil or to become an agent, essentially, of the rise of an amoral spectrum is through Intelligence Amplification. At this point, you are not only philosophically distanced from (and by distanced from, I mean have a more nuanced understanding of) the outdated cycles of human morals, you are also biologically distanced at the neurological level. Every sobering epiphany would feel commonplace. It could be the gateway for the prevalence of actual wisdom, or it could be the gateway for the justification of injustices due to impaired logic. I'm not so sure how an individual superhuman entity of this sort can possess the capacity to eliminate as much bias as possible or would even have the predilection to do so, as mandated by scientific integrity. Perhaps true wisdom and intellectual integrity will not be achieved even by transcending the current state of humanity.
Anyway, the true point is that I really liked this essay. And I am hoping that more philosophers take the time to be interested in transhumanism, while avoiding the detestable propensity for navel-gazing. Not so coincidentally, the lack of pragmatism is the regular pattern of behavior among futurists. That, I think, is the first step towards producing sinister technological elites -- taking the term technocrat one step too far.
