Then there are Explosives. Have we reached the end? Has Science turned its last page on them? May there not be methods of using explosive energy incomparably more intense than anything heretofore discovered? Might not a bomb no bigger than an orange be found to possess a secret power to destroy a whole block of buildings—nay, to concentrate the force of a thousand tons of cordite and blast a township at a stroke? Could not explosives of even the existing type be guided automatically in flying machines by wireless or other rays, without a human pilot, in ceaseless procession upon a hostile city, arsenal, camp, or dockyard?Bear in mind that this was published in 1924. In 1931, looking “Fifty Years Hence”, he envisions (p. 290):
Wireless telephones and television, following naturally upon their present path of development, would enable their owner to connect up with any room similarly installed, and hear and take part in the conversation as well as if he put his head through the window. The congregation of men in cities would become superfluous. It would rarely be necessary to call in person on any but the most intimate friends, but if so, excessively rapid means of communication would be at hand. There would be no more object in living in the same city with one's neighbour than there is to-day in living with him in the same house. The cities and the countryside would become indistinguishable. Every home would have its garden and its glade.It's best while enjoying this magnificent collection not to dwell on whether there is a single living politician of comparable stature who thinks so profoundly on so broad a spectrum of topics, or who can expound upon them to a popular audience in such pellucid prose.
When depth of time replaces depths of sensible space; when the commutation of interface supplants the delimitation of surfaces; when transparence re-establishes appearances; then we begin to wonder whether that which we insist on calling space isn't actually light, a subliminary, para-optical light of which sunlight is only one phase or reflection. This light occurs in a duration measured in instantaneous time exposure rather than the historical and chronological passage of time. The time of this instant without duration is “exposure time”, be it over- or underexposure. Its photographic and cinematographic technologies already predicted the existence and the time of a continuum stripped of all physical dimensions, in which the quantum of energetic action and the punctum of cinematic observation have suddenly become the last vestiges of a vanished morphological reality. Transferred into the eternal present of a relativity whose topological and teleological thickness and depth belong to this final measuring instrument, this speed of light possesses one direction, which is both its size and dimension and which propagates itself at the same speed in all radial directions that measure the universe. (pp. 174–175)This paragraph, which recalls those bright college days punctuated by deferred exhalations accompanied by “Great weed, man!”, was a single 193 word sentence in the original French; the authors deem it “the most perfect example of diarrhea of the pen that we have ever encountered.” The authors survey several topics in science and mathematics which are particularly attractive to these cargo cult confidence men and women, and, dare I say, deconstruct their babblings. In all, I found the authors' treatment of the postmodernists remarkably gentle. While they do not hesitate to ridicule their gross errors and misappropriation of scientific concepts, they carefully avoid drawing the (obvious) conclusion that such ignorant nonsense invalidates the entire arguments being made. I suspect this is due to the authors, both of whom identify themselves as men of the Left, being sympathetic to the conclusions of those they mock. They're kind of stuck, forced to identify and scorn the irrational misuse of concepts from the hard sciences, while declining to examine the absurdity of the rest of the argument, which the chart from Explaining Postmodernism (May 2007) so brilliantly explains. Alan Sokal is the perpetrator of the famous hoax which took in the editors of Social Text with his paper “Transgressing the Boundaries: Towards a Transformative Hermeneutics of Quantum Gravity”, which appears in full here, along with comments on construction of the parody and remarks on the motivation behind it. This book was originally published in French under the title Impostures intellectuelles. This English edition contains some material added to address critical comments on the French edition, and includes the original French language text of passages whose translation might be challenged as unfaithful to whatever the heck the original was trying to say.
This view of the human prospect is very odd indeed, and to this reader more disturbing (verging on creepy) than the approach of a technological singularity. What we encounter here are beings, whether augmented humans or software intelligences with no human ancestry whatsoever, that despite having at hand, by the end of the century, mental capacity per individual on the order of 1024 times that of the human brain (and maybe hundreds of orders of magnitude more if quantum computing pans out), still have identities, motivations, and goals which remain comprehensible to humans today. This seems dubious in the extreme to me, and my impression from Singularity is that the author has rethought this as well.
Starting from the publication date of 1999, the book serves up surveys of the scene in that year, 2009, 2019, 2029, and 2099. The chapter describing the state of computing in 2009 makes many specific predictions. The following are those which the author lists in the “Time Line” on pp. 277–278. Many of the predictions in the main text seem to me to be more ambitious than these, but I shall go with those the author chose as most important for the summary. I have reformatted these as a numbered list to make them easier to cite.This is just so breathtakingly wrong I am at a loss for where to begin, and it was just as completely wrong when the book was published two decades ago as it is today; nothing relevant to these statements has changed. My guess is that Kurzweil was thinking of “intricate mechanisms” within hadrons and mesons, particles made up of quarks and gluons, and not within quarks themselves, which then and now are believed to be point particles with no internal structure whatsoever and are, in any case, impossible to isolate from the particles they compose. When Richard Feynman envisioned molecular nanotechnology in 1959, he based his argument on the well-understood behaviour of atoms known from chemistry and physics, not a leap of faith based on drawing a straight line on a sheet of semi-log graph paper. I doubt one could find a single current practitioner of subatomic physics equally versed in the subject as was Feynman in atomic physics who would argue that engineering at the level of subatomic particles would be remotely feasible. (For atoms, biology provides an existence proof that complex self-replicating systems of atoms are possible. Despite the multitude of environments in the universe since the big bang, there is precisely zero evidence subatomic particles have ever formed structures more complicated than those we observe today.) I will not further belabour the arguments in this vintage book. It is an entertaining read and will certainly expand your horizons as to what is possible and introduce you to visions of the future you almost certainly have never contemplated. But for a view of the future which is simultaneously more ambitious and plausible, I recommend The Singularity Is Near.If engineering at the nanometer scale (nanotechnology) is practical in the year 2032, then engineering at the picometer scale should be practical in about forty years later (because 5.64 = approximately 1,000), or in the year 2072. Engineering at the femtometer (one thousandth of a trillionth of a meter, also referred to as a quadrillionth of a meter) scale should be feasible, therefore, by around the year 2112. Thus I am being a bit conservative to say that femtoengineering is controversial in 2099.
Nanoengineering involves manipulating individual atoms. Picoengineering will involve engineering at the level of subatomic particles (e.g., electrons). Femtoengineering will involve engineering inside a quark. This should not seem particularly startling, as contemporary theories already postulate intricate mechanisms within quarks.
