In 'Radical Technologies,' Adam Greenfield casts a discerning eye on the smartphone, an object so ubiquitous it has become almost invisible. He starts by painting a picture of the pre-smartphone era, drawing on ethnographic research from 2005, a world where pockets and purses were filled with a variety of discrete objects—keys, wallets, maps—each serving a specific purpose. Greenfield notes how the smartphone has swallowed these functions, dematerializing them into a digital dance of ones and zeroes. The author illustrates how the smartphone's absorption of everyday technologies deprives us of distinct urban sites, gestures, and practices. It's not simply a matter of better or worse, but a profound shift in our relationship to the world, and Greenfield urges us to take note of the consequences. He reveals that our most basic tasks now involve a complex web of actors, from manufacturers to regulators, making our competence contingent on obscure factors. The conventions of everyday life evolve at the pace of digital innovation, forcing us to constantly adapt. Greenfield suggests that when diverse pursuits all begin with launching an app on the same device, a certain sameness colors them, leading to a twitchy existence of never fully settling. He then dissects the smartphone's anatomy, from its aluminosilicate glass to its GPS chip, revealing how each component conditions our interaction with the world. The device, Greenfield emphasizes, is incomplete at the time of purchase, requiring provisioning and apps to unlock its potential, ultimately drawing us into a corporate ecosystem. He doesn't shy away from the darker side, exposing the troubling labor conditions and environmental damage embedded in the smartphone's production. The author acknowledges that we often suppress these qualms, driven by our desire for connectivity, yet he implores us to consider the ethical implications. Greenfield uses the example of digital maps to illustrate how the smartphone transforms our relationship to place, offering real-time navigation but also making us reliant on a vast, often invisible infrastructure. The blue dot on the screen, he argues, is a tangible way of engaging something much subtler, something over which we have virtually no meaningful control. The maps, while helpful, are not objective; they are tailored by algorithms, presenting each user with a different, separate lifeworld. Greenfield warns that this creates a digital divide, where access to networked services amplifies opportunities for some while excluding others. Ultimately, the smartphone is not just a device but a network organ, blurring the lines between self and the world. Like Churchill's observation about buildings shaping us, Greenfield concludes that we make networks, and they, in turn, shape us, creating a new kind of subjectivity, one where we are both here and somewhere else, joined to everything yet never fully anywhere at all, forever bathing in the primal rush of communion.

In "Radical Technologies," Adam Greenfield casts a discerning eye upon the burgeoning "internet of things," revealing not just a technological frontier, but a profound colonization of everyday life by information processing. Greenfield begins by painting a vivid picture of this planetary mesh—a bus in Copenhagen optimizing its route, a vulnerable webcam in Davao City exposing private moments, an engineer in San Francisco quantifying his very existence. He highlights that the core ambition driving the internet of things is a desire to elevate awareness of everyday circumstances to the network, a pursuit fueled by commercial differentiation, infrastructure management, and, inevitably, surveillance. Greenfield then dissects this phenomenon across three scales: the quantified self, the smart home, and the smart city, each illuminating distinct facets of this technological challenge. He notes the quantified self movement, with its promise of self-knowledge through numbers, often overlooks the brutal regime of efficiency it imposes, reshaping individuals into fungible production units. The smart home, epitomized by Amazon's Dash Button, aims to eliminate the space between desire and fulfillment, a convenience that comes at the cost of surrendering data and autonomy. The smart city, envisioned as a perfectly knowable and controllable entity, embodies an unreconstructed logical positivism, a belief in a single, transcendent solution to urban problems—an idea Greenfield finds deeply problematic. The author reminds us that every connected device presents a potential vulnerability, an attack vector, and that the reigning internet security paradigm is ill-equipped to handle the billions of cheap, insecure devices flooding the market. He urges us to see these connected things as sites of contention, where our interests clash with those of manufacturers, service providers, and even malicious actors. Greenfield warns that the data we shed onto the internet of things can be weaponized, as demonstrated by the Dutch experience during the Nazi occupation, where demographic records were used to devastating effect. Ultimately, Greenfield paints a somber portrait of the internet of things, an attempt to paper over the voids between us, a project driven by a technical elite with imperial designs on the everyday. He implores us to approach this technology with skepticism, resisting its siren call of ease and convenience, and questioning the vision of universality it promotes, for history suggests that data, once surrendered, can be turned against us in ways we cannot foresee. Like the quiet hum of unseen servers, the internet of things promises efficiency, but whispers of a deeper, more pervasive sadness, a melancholy born of shattered attention and eroded intimacy.

In 'Radical Technologies,' Adam Greenfield explores augmented reality (AR) as more than just a technological novelty, but as a profound shift in how we perceive and interact with our environment. He begins with the case of Shayla Wiggins, who stumbled upon a dead body while playing Pokémon Go, illustrating the surreal blending of physical and virtual realities that AR creates. Greenfield explains that AR, unlike virtual reality, overlays digital information onto our existing world, creating a 'reality shear' that can lead to both wonder and unforeseen consequences. The initial promise of AR, from military head-up displays to aiding engineers, was to enhance our perception and reaction in complex environments, yet the advent of smartphones has democratized this technology, bringing both its potential and its perils to the forefront. However, Greenfield cautions that the seductiveness of AR, with its aura of omnipotence, masks significant challenges. He questions whether AR can truly enhance social interactions, citing the awkwardness of using a phone to recognize faces, a process fraught with technical and privacy concerns. He then considers AR's potential to enrich our understanding of history by layering the past onto the present, envisioning a 'soft rain of names' over places touched by history, but acknowledges the practical limitations of current handset-based technology. Greenfield argues that the true value of AR lies in its immediacy, a sense of effortless information assimilation, something that wearable devices like Google Glass aimed to provide, yet these too, raise concerns about privacy, data security, and potential physiological dependence. Ultimately, Greenfield warns against the uncritical embrace of AR, highlighting the risks of divided attention, the erosion of public space, and the potential for a society where access to information is unequally distributed, creating a two-tiered reality. The core tension lies in balancing the promise of enhanced perception with the potential for social fragmentation and the loss of a shared reality. Greenfield urges us to consider whether we are trying to augment or escape from, emphasizing that true reality is the shared ground from which we build understanding and connection, a space that should not be splintered by technology.

In Adam Greenfield's exploration of digital fabrication, we begin with the image of a MakerBot Replicator 2, a humble box holding the potential to revolutionize manufacturing. Greenfield traces the lineage of this technology back to John von Neumann's vision of self-replicating automata, a vision realized in Adrian Bowyer's RepRap project, which sought to democratize production. The central tension emerges: can a $2,000 printer truly spark a revolution? Greenfield navigates arguments suggesting digital fabrication's power to erode capitalism by driving production costs to near zero, potentially defeating material scarcity. Yet, the path isn't straightforward, as ultra-low-cost production hinges on distributed availability, on-demand creation, material agnosticism, and circular waste recovery—criteria proving elusive. The narrative then considers whether digital fabrication can be meaningfully distributed, questioning if these technologies can escape the concentrated factory model, and highlights the necessity of accessible, welcoming spaces, overcoming the intimidation factor that limits broader adoption. The author underscores the need for material diversity, and the challenge of assembling complex objects, acknowledging that even in an age of on-demand fabrication, human labor remains essential. The chapter then grapples with sustainability, questioning whether widespread production aligns with ecological needs and proposes a circular economy model, emphasizing waste recovery and adaptive upcycling. However, the high cost of feedstock and access to free specifications remain significant hurdles, threatening to undermine the promise of democratized production. As Greenfield considers the allure of forbidden things, he cites Cody Wilson's Liberator pistol as a stark example of fabrication circumventing regulation, while also critiquing 'digital vanguardism,' where the ideological commitment to fabrication overshadows a community's immediate needs, evidenced by the failed Fablab experiment in Barcelona. Ultimately, the chapter suggests that the true essence of digital fabrication lies not merely in satisfying material needs, but in empowering individuals to devise their own solutions, fostering a shift from dependence to self-reliance, but a shift that requires careful navigation to avoid capture by existing systems of exploitation. The future hinges on a commitment to shared value, invitational accessibility, and a recognition that control over matter is intrinsically linked to the distribution of power, offering a glimpse of a world where the baleful magic of consumerism begins to fade.

Adam Greenfield embarks on a journey to demystify the complex world of cryptocurrency, particularly Bitcoin, for the uninitiated. He begins by acknowledging the initial bewilderment many experience when first encountering blockchain technology, a confusion stemming from its intricate nature and unique assumptions about human behavior. Greenfield draws a parallel to how we often grasp new technologies through familiar analogies, yet finds that Bitcoin resists such easy comparisons. The author illuminates Bitcoin's core innovation: replacing trust in intermediaries with cryptographic proof, enabling transactions authenticated by a global network of peers. This shift, Greenfield argues, has ignited interest because it promises to liberate us from relying on traditional institutions to guarantee commitments. He paints a vivid picture of how each Bitcoin and user possesses a unique cryptographic signature, tracing the coin's custody through time, all verified across a distributed network. Greenfield reveals that the complex process of validating transactions, known as mining, incentivizes distributed work while deterring forgery through a proof-of-work system, rewarding miners with freshly minted coins. However, Greenfield cautions against the early hype, pointing out Bitcoin's shortcomings as a stable store of value and its limited utility in everyday exchanges, hampered by high latency and a challenging user experience. The author then shines a light on a crucial, often overlooked issue: the thermodynamic cost of proof-of-work, revealing the staggering amount of energy consumed by Bitcoin mining, turning the atmosphere into a giant heatsink. Ultimately, Greenfield suggests that Bitcoin's lasting value lies not in its functionality as a currency, but as a catalyst for exploring new models of organization, coordination, and cooperation, paving the way for a robust, programmable trust infrastructure. Greenfield leaves us with a call to carefully assess the power dynamics and implications of these emerging technologies as we integrate them into our lives, urging us to sift through the possibilities with exceeding care.

In 'Radical Technologies,' Adam Greenfield navigates the complex landscape of blockchain technology, venturing beyond the initial hype surrounding Bitcoin to explore the more profound implications of distributed ledger systems. He observes that while Bitcoin's promise of a universal digital currency has yet to materialize, the underlying blockchain technology presents a powerful and general vocabulary for building new kinds of systems. Greenfield introduces Vitalik Buterin, the mind behind Ethereum, as a pivotal figure who recognized Bitcoin's limitations and envisioned a programmable blockchain capable of much more than simple value transfer. Ethereum, Greenfield explains, functions as a decentralized computing engine, enabling the creation of smart contracts—self-executing agreements written in code. These smart contracts, initially conceived by Nick Szabo, promise to automate and enforce agreements without the need for traditional legal frameworks, yet their reliance on digital assets creates a boundary with the physical world. Greenfield illustrates this with the example of Sayalee Kaluskar and Gaurang Torvekar's blockchain-based prenuptial agreement, highlighting the challenges of enforcing real-world obligations through code. The author then turns to the concept of Distributed Autonomous Organizations (DAOs), envisioning them as new forms of collective action, but acknowledges the potential for these organizations to be captured by powerful institutions or to exacerbate existing inequalities. Greenfield warns of the dangers of a fully privatized governance, where only those versed in the arcana of cryptofinance can prevail, contrasting this with the principles of the commons, which emphasize interdependence and shared responsibility. The narrative tension crescendos with the real-world example of The DAO, a distributed venture capital fund that suffered a major security breach, exposing the vulnerabilities and governance challenges inherent in these nascent technologies, revealing that the promise of decentralization risks collapsing under the weight of human nature. Ultimately, Greenfield urges a cautious but open-minded approach to blockchain technology, recognizing its potential for both utopian and dystopian outcomes, and underscoring the need for critical engagement to ensure that these technologies serve the broader interests of humanity rather than merely amplifying existing power structures, a technology that glitters with promise but risks solidifying the very structures it aims to dismantle, leaving us in a world where the unnecessariat are left behind.

Adam Greenfield paints a stark picture of a future shaped by automation, a world where the very essence of work, identity, and daily rhythms are transformed. He begins by highlighting our present-day augmented capabilities, a superhuman existence we often take for granted until its disruption reveals our dependence. The central tension emerges: despite our technological prowess, fundamental limits persist, fueling the drive to create systems exceeding human capabilities. Greenfield challenges the naive optimism surrounding automation, dissecting the motivations behind its relentless pursuit. He argues that the promise of relieving humans from 'dull, dirty, difficult, or dangerous' jobs often masks a more pragmatic desire for a cheaper, more compliant labor force. Like a relentless tide, automation creeps into professional and managerial roles, threatening the livelihoods of many. The author cautions against underestimating the speed and thoroughness of this transformation, urging us to confront its implications for the economy and society. He introduces the concept of the 'posthuman everyday,' a world where the needs of systems overshadow human desires, and challenges us to consider what kind of relationship we want to have with these technologies. Greenfield then deconstructs the common justifications for automation, revealing a complex interplay of intellectual curiosity, commercial interests, and a sometimes-cynical disregard for human dignity. He acknowledges the potential benefits, such as increased safety and reduced bias, but also warns of the dangers of unchecked technological advancement. The image of a lone truck driver, once a symbol of American self-reliance, now stands as a stark reminder of the jobs vulnerable to automation. Greenfield dispels the myth that technology will inevitably create more jobs than it destroys, pointing to the devastating impact of autonomous trucking and robotic warehousing. He anticipates a grim future for those who remain in the workforce, characterized by increased demands, lower wages, and constant surveillance. The author also touches upon the rise of algorithmic management and performance monitoring, where every aspect of an employee's behavior is tracked and analyzed, potentially leading to a dehumanizing work environment. He envisions a world where even emotional states are measured and manipulated, blurring the lines between personal and professional life. Ultimately, Greenfield questions the long-term consequences of automation, challenging the utopian visions of total leisure and universal basic income. He suggests that the disappearance of work may lead to a loss of meaning, purpose, and social connection, leaving us ill-equipped to navigate a world without obligation. The chapter concludes with a call for a reinvention of left politics, one that recognizes the need for solidarity and support for a 'near-universal unnecessariat,' and considers what an economy might be for, if not the generation and apportionment of wealth as humans experience it.

In "Radical Technologies," Adam Greenfield explores the complex world of machine learning, beginning with a fundamental question: what *is* data? He positions it as facts collected to inform action, yet emphasizes that data is never truly raw; it's always a curated subset of reality, a selection, much like our own senses filter the world. Greenfield elucidates how algorithms, those finite and explicit instruction sets, sift through this data, governing everything from streaming recommendations to creditworthiness. The tension arises when these algorithms, designed to adapt and learn, begin to shape society in profound ways. Greenfield notes that as circumstances evolve, static algorithms falter, highlighting the necessity for machine learning—the ability to learn from experience and generalize insights, a process akin to teaching algorithms to recognize patterns in the world through vast datasets. He masterfully demystifies neural networks, explaining how they mimic the human brain's layered perception, processing stimuli from basic features to complex recognitions, and emphasizes that machine learning teaches algorithms how to generalize, deriving classifiers from encountered data. Yet, the danger of overfitting—memorizing data instead of generalizing—looms large, alongside the insidious presence of bias, where algorithms fail to grasp essential qualities, leading to skewed or discriminatory outcomes. Greenfield cautions that even with corrections, small or homogeneous training sets limit perception, creating skewed realities, like Google's Deep Dream software, initially trained on canine breeds, seeing dogs everywhere. He uses the tragic story of Joshua Brown, the first known fatality involving Tesla's Autopilot, to illustrate the perils of over-reliance on automated systems, revealing a critical gap between the function's capabilities and the implicit premise of complete autonomy. Greenfield warns that the tacit bargain of automation involves relinquishing discretion for perceived performance, a trade-off demanding careful consideration, especially when applied to public safety, as seen in predictive policing. He then critiques tools like Snaptrends and PredPol, questioning their potential for mission creep and the criminalization of mere presence, not behavior, which leads to a path dependence where past data overly determines future actions. Greenfield argues that this creates a dangerous loop, and emphasizes that the design of algorithms involves human discretion, and that choices have profound consequences. The author challenges the notion of escaping politics through math, arguing that algorithmic tools merely reflect existing societal power structures. Ultimately, Greenfield underscores the risk of overtransparency, where the surfacing of uncomfortable truths causes social friction and harm, eroding privacy and freedom of assembly. He warns that as algorithmic power grows, our ability to inspect and understand their judgments diminishes, creating an asymmetry where those who control the algorithms know far more about us than we know about them. The chapter concludes with a call for algorithmic accountability, yet acknowledges the difficulty of achieving it, given the complexity and opacity of these systems, leaving us to wonder if we are building a world where patterns of advantage and resource allocation will be forever beyond our comprehension, or if the human spirit can summon the courage to confront the consequences of these technologies with integrity.

In 'Radical Technologies,' Adam Greenfield guides us to the edge of the human, a place where artificial intelligence, despite its often arrogant and reductionist origins, becomes competent to interpret and purposefully intervene in the world. Greenfield illuminates a central tension: while AI's proponents redefine its boundaries as goals are met, many cling to the hope that uniquely human creative tasks will remain beyond its reach. Yet, the essence of learning, whether human or machinic, lies in pattern recognition and reproduction. Greenfield confronts the uncomfortable truth that even the greatest works of art consist of patterns, challenging the notion of some ghostly inspiration beyond algorithmic capture. Consider Nina Simone's ache and steel, seemingly impossible to flatten into instructions, yet even her phrasing yields to analysis. The Next Rembrandt project exemplifies this, reanimating a master's style through data, raising questions of consent and innovation. AlphaGo's mastery of Go, a game of unfathomable complexity, further blurs the lines, its moves sometimes surpassing human intuition, leaving observers unsettled. Greenfield notes, it's not just about replicating mastery but transcending it, as seen in the unnerving smoothness of drone footage or the Lovecraftian designs of topologically optimized brackets. As AI pushes past human standards, it elicits surges of delight and also a numbing sense of being worn down. He acknowledges AI's current limitations, such as natural language processing and autonomous vehicle navigation, but warns against complacency, reminding us of AlphaGo's rapid learning and the continuous refinement seen in Tesla's Autopilot. The lesson is clear: autonomous algorithmic systems are rapidly approaching human-level cognitive capability, potentially introducing a factor of infinity into our understanding of the world, creating both beauty and sadness in equal measure, a time of great change we have already entered.

In "Radical Technologies," Adam Greenfield casts a discerning eye on our present, where algorithm-recommended cafes and cryptocurrency payments barely raise an eyebrow, yet he urges us to recognize that the true transformation lies not in isolated technologies, but in their convergence. Greenfield illuminates how these technologies, speaking the universal language of code, are modular, reusable, and rapidly evolving, like Lego bricks building ever more complex structures. He cautions, however, that the values embedded within this code travel with it, influencing every application. Greenfield introduces us to the 'Stacks'—tech giants like Apple, Amazon, Google, and Facebook—vertically integrated entities vying for control over our digital lives, yet fractured by internal rivalries and the inherent unpredictability of human organizations. A crucial insight emerges: the seamlessness we perceive is often a mirage, a testament to the chaotic reality within these behemoths. Amazon, Greenfield suggests, may be the most integrated Stack, weaving drones, robotics, and the Internet of Things into a single, data-hungry apparatus, a vision so ambitious it threatens to redefine retail itself. The author then considers the startup ecosystem, a vast distributed R&D lab fueled by the Stacks' acquisitions, a landscape where innovation flourishes alongside pointless or offensive ideas, challenging any coherent ethical framework. It's a world where monetization trumps morality, and the potential for misuse lurks behind every line of code, a constant tension between progress and peril. Greenfield paints possible futures, from the utopian 'Green Plenty' to the dystopian 'Perfect Harmony,' each a stark reminder that technology's trajectory is not predetermined but shaped by our choices. He challenges us to consider: what decisions must we make now to steer toward the outcomes we desire, and away from those we dread? The author reminds us that technology never operates in isolation, its impact amplified or constrained by existing social systems, human desires, and the ever-present currents of ideology, urging us to understand how these technologies truly work and who benefits most from their influence.

Adam Greenfield begins with the image of tetrapods—concrete structures designed to prevent beach erosion in Japan—as a metaphor for technology's unintended consequences. He cautions against technoutopian promises, suggesting that technologies, like the tetrapods, often fail to deliver on their intended benefits and can even exacerbate existing problems, becoming a subsidy for existing power structures. Greenfield invokes Stafford Beer's assertion that a system's purpose is what it does, not what it intends to do, urging critical evaluation of technologies based on their actual effects. He highlights examples like self-replicating digital fabricators and smart contracts, which, despite their liberatory intentions, have been captured or rejected by existing systems due to material recalcitrance and human nature. The author notes that while some technologies may disrupt the surface, they rarely challenge deeper power structures, and our commitment to networked technologies has become a kind of inescapable momentum. Greenfield then poses critical questions: Can these technologies be renounced or resisted, and can they be steered toward more congenial ends? Renunciation, he argues, is nearly impossible in our interconnected world, but resistance, even in small acts of infrapolitics, offers some hope. He stresses the importance of understanding how technology is produced and controlled, advocating for a deeper engagement with the institutional processes that shape our technological landscape. To conclude, Greenfield urges technologists and progressives to collaborate, challenging the rhetoric of transcendence and recognizing the human drives—profit and power—underlying technological advancements, lest we surrender to a shallow dream. Like ghostly data on an imperfectly erased hard drive, Greenfield reminds us that we must seek and cultivate seeds of solidarity, conviviality, and justice from the past, to sow a more considered and generous way of living together on Earth.

Radical Technologies paints a sobering portrait of our technologically mediated present and potential futures. The smartphone, IoT, AR, digital fabrication, crypto, automation, and AI, aren't merely tools but forces reshaping our lives, often invisibly. Convenience masks profound ethical and societal shifts. We're increasingly reliant on systems that erode privacy, autonomy, and potentially, individuality. The promise of algorithmic solutions often overlooks human complexity and reinforces existing power structures. Greenfield urges critical engagement: dissect assumptions, question motivations, and resist the allure of technological transcendence. The future isn't predetermined; it's shaped by our choices. We must prioritize solidarity, justice, and mindful integration to ensure technology serves humanity, not the other way around. It's a call for a considered and generous way of living together on Earth.
