On The Connectivity of Things: Network Cultures since 1832
What is the truth about the network? And what might it tell us in our current situation? After five years of translation and fine-grained updating, Sebastian Giessmann’s seminal book on The Connectivity of Things: Network Cultures since 1832 finally came out in October 2024 with MIT Press. The full text is available in open access.
While the translated book’s historical narrative is deeply rooted in developments of 19th and 20th century infrastructural history, it is also a key work of German media theory. There’s much to discuss here for historians of technology, be it the notion of “cultural techniques,” the seemingly Western grounding of network practice and thought, and the in/visible work of networking in material cultures itself.
Connectivity is a book full of in-depth case studies that deserve a closer look, be it the relation between networks and colonial power in the case of French Saint-Simonianism, be it the early history of the telephone network, visual histories of network diagrams, the mobilities of the London Tube Map, Western and Eastern styles of logistics, and the unlikely inception of the ARPANET. It might be said that networks are a core cultural technique to allow for the migration of people, signs, and objects, which includes their disconnection. Connectivity of Things finally gives us a history that actor-network theory never dared to write itself.
We invite everyone at SHOT in Luxembourg to join the discussion, both in person and per hybrid participation. Our author-meets-critics session will combine key critical questions towards the book, and shall provide insights into the intricacies of such an (un-)timely and complex translation endeavor.

Blockchain vs. AI
Both as imaginary and material network technologies, blockchain and ‘artificial intelligence’ tend to clash and mingle at the same time. Current neoconnectionist AI and blockchains follow very different cultural logics, just as neural networks differ from peer-to-peer networks sociotechnically. Maximum data intensity, large language models, tokenized media objects, modification of algorithms by data, operational statistics, plus the variation of existing patterns in the case of AI – data immutability, encryption, token economies and exact processing of algorithmic instructions in the case of blockchain. Together, blockchain and neoconnectionist AI are about to form what I call a seventh historical layer within my work on “The Connectivity of Things” in network cultures.
Yet, at the same time, blockchain and AI not only compete for parallel distributed processing power in data centers. They both share energy-intensive, extractive strategies that drive the booms and busts of too-late capitalism (Anna Kornbluh). While their network imaginaries are still being contested, naturalization and habitualization happen at an ever increasing pace. Sometimes, blockchain is now promoted as a slowing-down counter-infrastructure to AI’s accelerationist, generative media and its models. The paper is going to take a close look at controversial cases like Worldcoin, which is supposed to afford for a biometrical “proof-of-human” that attaches a digital identity to online content. While the cultural logics of blockchain and AI might seem to differ almost entirely on the infrastructural level, they are currently serving as a match made in hell when it comes to their political and economical appropriation.

Eineindeutigkeit. Digitale Aktenform und blockchainbasierte Transaktion
Der Beitrag rekonstruiert das Entstehen einer digitalen Aktenform im 21. Jahrhundert, mit der die eindeutige Nachvollziehbarkeit von Finanztransaktionen und Rechtsakten garantiert werden soll. Hierzu werden Blockchain-basierte Infrastrukturen – Bitcoin, Ethereum und Worldcoin – anhand der sie fundierenden technischen Whitepaper rekonstruiert und kontextualisiert. Gemeinsam ist diesen Infrastrukturen, wie auch dem PDF-Format, eine Produktion von ›Eineindeutigkeit‹, die grundsätzlich immer bearbeitbaren Daten einen fixen Wert zuschreibt. Gegenüber den intransparenten Akten generativer KI im maschinellen Lernen, so die These, bieten Blockchain-Medien die Option einer digitalen Fixierung, mit der alle möglichen sozialen, juristischen und ökonomischen Praktiken registriert und identifiziert werden.
Im Open Access erschienen als: Eineindeutigkeit. Digitale Aktenform und blockchainbasierte Transaktion. In: Plener, Peter/Wolf, Burkhardt (Hg.): Akte/n. Stuttgart: Metzler, 2025, S. 153–166.

Künstliche Intelligenz zwischen Spezialisierung und Universalisierung
Auf welche Zukunft in welchen neuen Umgebungen muss sich die Medien- und Kulturtechnikforschung angesichts der rezenten Konjunktur von Künstlicher Intelligenz ausrichten?
Der Vortrag kommt hierzu auf eine grundsätzliche Frage von Marcel Mauss zur Konstitution von Techniken zwischen speziellen und allgemeinen Zwecken zurück. Er bietet, erstens, eine kurze Lagebeschreibung zur gegenwärtigen Entwicklung des maschinellen Lernens und neuerer KI zwischen Spezialisierung und Universalisierung.
Kern meiner Argumentation ist, zweitens, eine natur- und kulturtechnische Genealogie. Sie fragt nach der historischen Wiederkehr konnektionistischer Praktiken, Algorithmen, Denk- und Handlungsstile als Bedingung der aktuellen KI-Technologien. Wie konnten aus biologischen Neuronen artifizielle neuronale Netze werden, die als infrastrukturelle Grundierung Künstlicher Intelligenz fungieren?
Auf dem Spiel stehen dabei, drittens, die Medien selbst. Sie werden aufgrund der Naturalisierung und Habitualisierung von konnektionistischer KI zu statistisch operationalisierten, datenintensiven Netzwerken.

Small Forms in Circulation
I am happy to give a keynote at this conference of the Research Training Group “The Literary and Epistemic History of Small Forms”. It is called Infrastructures and/as Environments: Practices and Ecologies of Circulation. Feel free to join us and think collectively about “Small Forms in Circulation” at Humboldt University on November 28-30, 2024.
Testing the Social Network
Blogging gets a bit harder throughout the start of the academic term. This is why I return to this series of image from The Connectivity of Things just now. Chapter 6 of the book tells a visual history of the network diagram. It follows the early history of graph theory in mathematics and chemistry. But the payoff here is a true crime history of sociology. While the name of Jacob Levy Moreno might sound familiar, the name of social psychologist Helen Hall Jennings is largely unknown even to scholars of social networks. Yet, it was Jennings who provided Moreno with a set of innovative methods to gather data on social relations. The sociometric test is what allowed for a visual formalization of a given network’s data. While Jennings still had a chapter of her own in the 1934 first edition of Moreno’s book Who Shall Survive, her work was hidden in a list of (numerous) references in the second edition of 1953. This is why I have started to reference both versions as written by Moreno and Jennings.
In the 1953 second edition, Moreno also made strong claims regarding “his” visual method of network visualization. A lot of the sociometric diagrams have been drawn by women though. Just consider an image like The Lady Bountiful, which was drawn by student assistant Pauline Lee in 1938. But in this case, Moreno’s copyright assertion for visualizing social networks has been more than mere rhetoric. His 1920s diagrams of stage movements in improvised theater (Das Stegreiftheater, 1924) can indeed be regarded as a crucial pathway towards visualizing dynamic social networks. But we should still be careful whom to give credit to when it comes to the methods of testing and visualizing social networks.

La science et la vie
There’s much to be said about this title page of the French journal La science et la vie. It comes with all the ambivalent connotations of gender, telephony, labor and automation history. We can still see a shadow of „la demoiselle du téléphone“ in the center of the image. Yet, the telephone girl or „Fräulein vom Amt“ has become a non-human switching machine in 1927. Experts of telephone infrastructure are going to notice the rotary selector and a stepping switch at the bottom of the image. Plus, the switching network in the center shows a line of alphabetic letters.
This circuit with letters points to an unusual feature of Paris telephone switchboards of the time. The first three letters of a telephone code indicated the telephone exchange. They were followed by four digits representing the person being called, which correspond here to the four dials of the “brain.” The seven-digit number could be entered using dials on which the twenty-five letters were printed.
Besides this technical dimension of social addressing, this title page also invokes older, reticular representations of networks. Blue and red lines remind us of the color conventions in anatomy and blood circulation, and thus provide a rather corporeal link for the telephone call of a man and a woman. More on telephone networking can be found in chapter 5 of „The Connectivity of Things: Network Cultures since 1832.“

Charles Joseph Minard’s Statistical map of European railroad traffic
So I continue with another image that represents a significant entry in my network history The Connectivity of Things: Network Cultures since 1832. The book came out on October 15, by the way. Chapter 4 follows the twisted paths of Saint Simonianism. Yet, this week’s image is not as ambivalent as the rest of the chapter which deals with early socialism’s colonial ambitions. Polytechnicien Charles Joseph Minard’s 1862 statistical map of European railroad traffic rather underscores the Saint-Simonian ambitions for a mobilized industrial Europe. Minard’s other statistical maps and diagrams have become a classic in the history of visualizing information. But this image primarily expresses the ambitions of Saint-Simonianism to create a vibrating infrastructural network for the good of society.
