Critical Comments on Kaczynski’s “The Techies’ Wet Dreams”

June 12, 2026

IMPORTANT NOTE FROM ÚLTIMO REDUCTO: To fully understand and appreciate this text, it is recommended to first read “The Techies’ Wet Dreams”. And, even better, the reader should read Anti-Tech Revolution: Why and How in its entirety.


I will begin by clarifying that I do not consider Anti-Tech Revolution (ATR) to be a good book. I believe that this book and Kaczynski’s texts written at later dates are, among other things, a disaster regarding logic, theoretical coherence and rigor, and definition and use of terms. ATR is a mediocre book for mediocre minds that should have been titled Anti-Tech Revolution for Dummies.[1] I think that when Kaczynski wrote it, either his mental faculties were already in decline or, more likely, he deliberately lowered the bar for the intellectual quality of his arguments in order to reach a wider audience; a specific type of audience, not of very high caliber. And this text, corresponding to Part V of Chapter 2 of said book, is a good example of this. I’m going to comment on some of the specific flaws I see:


[1] In reality, the book doesn’t even reach that level. A typical “manual for dummies” is usually a guide, simplistic but more or less practical, with specific rules and advice on how to do something. However, Anti-Tech Revolution doesn’t even live up to its subtitle “How and Why” (and especially the “why”).

[2] Kaczynski used the term “techies” derogatorily to refer only to those particularly delusional and enthusiast technophiles who wholeheartedly believe in progress and proclaim the imminence of a technoutopia in which technology will allow, among other implausible things, the achievement of immortality. Note added by UR for this post.

[3] For example: “We need not doubt that it will be technically feasible in the future to keep a human body, or a man-machine hybrid, alive indefinitely”. Or “There is of course evidence to support many of the techies’ beliefs about particular technological developments, e.g. , their belief that … it will some day be technically feasible to keep a human body alive indefinitely”.

[4] For example: “No one is going to achieve immortality in any form”. “[The techies’] dream of immortality is illusory nonetheless”; “The seven-hundred-year or thousand-year life-span to which some techies aspire is nothing but a pipe-dream”.

[5] “It is seriously to be doubted that it will ever be feasible to ‘upload’ a human brain into electronic form with sufficient accuracy so that the uploaded entity can reasonably be regarded as a functioning duplicate of the original brain”; “the chances that any given techie will survive indefinitely are minute”; “Immortality in the form (i) -the indefinite preservation of the human body as it exits today is highly improbable”.

[6] In the text, Kaczynski distinguishes between three ways of achieving immortality:

(i) The indefinite preservation of the living human body as it exists today.

(ii) The merging of human beings with machines (cyborgs).

(iii) The “uploading” of human minds into robots or computers.

[7] This inherent human tendency to always express at least some degree of discord -to never reach total consensus (i.e., among all human beings) or act all (i.e., all human beings) together toward a common goal-, while due to the inherent diversity of human nature, is not even materially inevitable in principle. In theory, it might one day be possible to genetically modify all human beings to make them psychologically homogeneous and entirely prone to consensus and cooperation. Although then they would no longer be fully human…

With other factors, such as the intrinsic uncontrollability of complex systems or Darwinian selection among systems (or, as we will see, the second law of thermodynamics or “chance”), this possibility is not even theoretically feasible. They are physically inevitable.

[8] By the way, Kaczynski even falls short when it comes to listing and explaining these extrinsic factors that will prevent immortality. Thus, for example, as far as I know, neither Kaczynski, nor the technophiles, nor all the others who also place their hopes on achieving immortality someday, take into account such basic things as entropy (the second law of thermodynamics) or imponderable factors (what we tend to call “chance”).

Entropy, a fundamental tendency of the universe, implies that everything tends to degrade if no constant effort is made to repair and maintain it. In other words, things tend to wear out, age, and break down, including the human body, cyborgs, robots, and computers. And, more importantly, this tendency toward degradation also affects the very technological devices and systems developed to carry out repairs and maintenance. So much so that, ultimately, the tendency toward degradation and aging is always more powerful in the long run than any system’s capacity to prevent it and continue performing repairs and maintenance effectively indefinitely, if only because this tendency toward degradation always and inevitably occurs within these same repair systems as well.

And as for the imponderables, it’s simply a matter of statistics that sooner or later, every physical system that lasts indefinitely will suffer some kind of accident, destruction, attack, or breakdown—unforeseen, unpredictable, and “fatal.” In other words, given enough time, it’s a certainty that something unforeseen and unwanted will happen to any system, causing its structure to break down drastically and irreparably. It’s only a matter of time before, due to an accident, a war, a predator attack, a virulent disease, a failure in the repair system, etc., the structure of the system in question (be it a human body, a cyborg, a robot, or a computer) suffers damage so significant, extensive, and/or rapid that it becomes irreparable. For example, let’s imagine, for the sake of argument, that a person manages to survive for centuries through successive transplants of decaying body parts, their replacement with mechanical prostheses, or the downloading of their mind into a computer. At some point, this “person” (or what remains of him) will suffer an accident that completely destroys his body -biological or biological-mechanical-, or simply his brain or the computer housing his mind. A fire that incinerates it, a blow that shatters it, the fall of a great weight that completely crushes it, a shark that eats it while swimming at the beach (assuming that large predators still exist in the wild by then), etc. And that’s it! He’ll be dead anyway. Or, even more importantly, the systems responsible for maintaining these bodies, cyborgs, or computers will sooner or later suffer some unforeseen “fatal” damage (that is, damage severe enough to be definitively, completely, and irreparably destructive), which will cause the bodies, cyborgs, or computers to cease being maintained and repaired, and thus to stop functioning.

[9] “Spiritual” immortality is not worth discussing here, because it’s a purely metaphysical matter; that is, it’s a matter of pure faith.

[10] For example, see: “[H]aving successfully raised his children, going through the power process by providing them with the physical necessities, the primitive man feels that his work is done and he is prepared to accept old age (if he survives that long) and death. Many modern people, on the other hand, are disturbed by the prospect of death, as is shown by the amount of effort they expend trying to maintain their physical condition, appearance and health. … It is the man whose need for the power process has been satisfied during his life who is best prepared to accept the end of that life” (“Industrial Society and Its Future” (ISAIF), paragraph 75) or “[O]ne has to balance the struggle and death against the loss of freedom and dignity. To many of us, freedom and dignity are more important than a long life or avoidance of physical pain. Besides, we all have to die some time, and it may be better to die fighting for survival, or for a cause, than to live a long but empty and purposeless life” (ISAIF, paragraph 168).

[11] See, for example: “Not that we have anything against social justice, but it must not be allowed to interfere with the effort to get rid of the technological system” (ISAIF, paragraph 201).

[12] Although it is also obvious that Kaczynski never, not even in his best period and his best writings (for example, “ISAIF”), took enough time to think about and clarify these ideas and values and to try to define and formulate them rigorously and unequivocally, considering that investing much time and effort in it was “impractical.” And so ended up even his best writings (and ATR is not precisely one of them): with too many contradictions, ambiguities, oversimplifications, vagueness, misused terms and expressions, etc. Beneath a superficial veneer of precision, rigor, and logical coherence.

[13] “By a self-propagating system (self-prop system for short) we mean a system that tends to promote its own survival and propagation. A system may propagate itself in either or both of two ways: The system may indefinitely increase its own size and/or power, or it may give rise to new systems that possess some of its own attributes” (ATR, Chapter Two, Ficht & Madison, 2016, page 42).

[14] In fact, it does not in any way affect the validity or invalidity of Kaczynski’s argument that Technianity, like Marxism or Christianity, has its own Chosen Ones –the Elect. What difference does it make actually whether the Elect of each of these movements are many or few, a majority or a minority?

[15] One might also wonder what on earth Kaczynski meant by “direct” in this case. Is there such a thing as “indirect” descent in evolution?

[18] Incidentally, it is very difficult to unequivocally prove/disprove Benton’s statement based on the fossil record (and that would be the only clear way to prove/disprove it). If only because it is impossible to know exactly how many species have existed throughout the history of life on Earth (in fact, we cannot even know exactly how many species exist today).
