The world is now enduring greater stress than any time in recent decades, according to U.N. Secretary-General António Guterres. And while humanity has so far avoided “the suicidal mistake of nuclear conflict,” he said, tensions are hitting new highs at a time when many lessons of the past seem forgotten.
“Today, humanity is just one misunderstanding, one miscalculation away from nuclear annihilation,” the world’s top diplomat said at a U.N. conference on the non-proliferation of nuclear weapons in New York City.
It’s not the first time such a dire warning has been issued about the catastrophic risks posed by nuclear weapons. Here’s a brief look at why Guterres and others are raising the alarm now: LINK
Modafinil is an eugeroic drug that has been examined to maintain or recover wakefulness, alertness, and cognitive performance when sleep deprived. In a nonmilitary context, the use of modafinil as a nootropic or smart drug, i.e., to improve cognitive performance without being sleep deprived, increases. Although cognitive performance is receiving more explicit attention in a military context, research into the impact of modafinil as a smart drug in function of operationality is lacking. Therefore, the current review aimed at presenting a current state-of-the-art and research agenda on modafinil as a smart drug. Beside the question whether modafinil has an effect or not on cognitive performance, we examined four research questions based on the knowledge on modafinil in sleep-deprived subjects: (1) Is there a difference between the effect of modafinil as a smart drug when administered in repeated doses versus one single dose?; (2) Is the effect of modafinil as a smart drug dose-dependent?; (3) Are there individual-related and/or task-related impact factors?; and (4) What are the reported mental and/or somatic side effects of modafinil as a smart drug?
Method
We conducted a systematic search of the literature in the databases PubMed, Web of Science, and Scopus, using the search terms “Modafinil” and “Cognitive enhance*” in combination with specific terms related to the research questions. The inclusion criteria were studies on healthy human subjects with quantifiable cognitive outcome based on cognitive tasks.
Results
We found no literature on the impact of a repeated intake of modafinil as a smart drug, although, in users, intake occurs on a regular basis. Moreover, although modafinil was initially said to comprise no risk for abuse, there are now indications that modafinil works on the same neurobiological mechanisms as other addictive stimulants. There is also no thorough research into a potential risk for overconfidence, whereas this risk was identified in sleep-deprived subjects. Furthermore, eventual enhancing effects were beneficial only in persons with an initial lower performance level and/or performing more difficult tasks and modafinil has an adverse effect when used under time pressure and may negatively impact physical performance. Finally, time-on-task may interact with the dose taken.
Discussion
The use of modafinil as a smart drug should be examined in function of different military profiles considering their individual performance level and the task characteristics in terms of cognitive demands, physical demands, and sleep availability. It is not yet clear to what extent an improvement in one component (e.g., cognitive performance) may negatively affect another component (e.g., physical performance). Moreover, potential risks for abuse and overconfidence in both regular and occasional intake should be thoroughly investigated to depict the trade-off between user benefits and unwanted side effects. We identified that there is a current risk to the field, as this trade-off has been deemed acceptable for sleep-deprived subjects (considering the risk of sleep deprivation to performance) but this reasoning cannot and should not be readily transposed to non-sleep-deprived individuals. We thus conclude against the use of modafinil as a cognitive enhancer in military contexts that do not involve sleep deprivation.

I love a good story from a time before history, even if it’s not really from a time before history.
Or is it?
I have recommended the work of Julian Langer a few times, as you probably remember, and this is another of those times.
Julian has crafted a wonderful “tale of the tribe” with his new work, Bretannike Rebellion.
It’s a nice, light, summer read that is short content-wise but long on thoughtfulness.
Julian and I see eye to eye on many philosophical and environmental issues, and my alter ego, Ezra Buckley, also approves of his work.
I don’t want to ruin the revelation of the work for you personally because I hate when reviewers talk too much about someone else’s work they are recommending, so in the interest of brevity, I’ll simply say, read it.
The tale is entertaining while also being thought-provoking, and the accompanying poetry pieces alone are worth the time investment.
Fisher feared that we were losing our ability to conceptualize a tomorrow that was radically different from our present.Photograph by Georg Gatsas / Verso Books
Mark Fisher was a writer and academic from the English Midlands who, in the early two-thousands, felt at odds with many of the institutions around him. Fisher, then in his mid-thirties, had devoted himself to theories of capitalism and Internet culture that few people in his immediate vicinity appeared to care about. He was zealous about obscure music and cinema at a time when critical discourse seemed to be reorienting itself around our biggest stars. So, in 2003, he decided to start a blog.
Fisher’s blog was called K-Punk. The K came from kyber, the Greek root of “cyber,” and it was intended to signal his interest in a time before the rise of the sort of cyber boosterism that Fisher associated with Wired magazine. Punk, for Fisher, was a way of being and seeing that involved a refusal of things as they were. The blog would be a place to workshop and refine ideas, and a forum for debates that seemed marginal within academia but too dense for mainstream magazines.
Blogging, in those days, at its best, seemed like a distinct genre of writing and thinking. Fisher’s posts were adventurous and idiosyncratic, chasing allusions across his bookshelf, record collection, and multiple screens—a riff on Ronald Reagan, for instance, might be routed through Jonathan Swift, the Dadaists, and Fredric Jameson. K-Punk gave Fisher space to revisit past enthusiasms: the hyperactive dance singles, experimental filmmakers, and pulp novels that had rewired his outlook when he was growing up in Margaret Thatcher’s nineteen-eighties. He revisited some of these influences—the author J. G. Ballard, the philosopher Slavoj Žižek—frequently enough that, if you were a regular reader of the blog, they became a part of your world view, too.
But if there was a single theme around which K-Punk’s eclectic energies organized, it was the future. Specifically: What happened to it? Fisher feared that we were losing our ability to conceptualize a tomorrow that was radically different from our present.
K-Punk attracted an avid readership, and, in 2009, Fisher published “Capitalist Realism,” a slim, powerful book about “the widespread acceptance that there is no alternative to capitalism.” Fisher saw signs of exhausted resignation in everything from the faces of his students to grim Hollywood movies set in the near-future (“Children of Men,” “Wall-E”) to “Supernanny,” a British reality show about parents unable to rein in their misbehaving kids. Fisher was interested not only in the political causes and cultural expressions of this exhaustion but in its emotional dimensions, too: the feelings of sadness or despondency that seem increasingly common across the political spectrum.
“Capitalist Realism” became a cult favorite in part because of the relentless energy of Fisher’s writing and in part on account of the rousing call to arms that he offered in its pages. “The tiniest event can tear a hole in the grey curtain of reaction which has marked the horizons of possibility under capitalist realism,” he writes. “From a situation in which nothing can happen, suddenly anything is possible again.”
