This guide walks a new reader through the project: the question driving it, its working vocabulary, the method, the cases that anchor it, the treatment of generative AI, and a route through the Notion workspace.
The project asks what Understanding Media would contain if McLuhan had written it with Jewish textual forms in view. Its starting observation is that Judaism has a history of texts and, running alongside it, a history of technologies for making texts present. This project follows that second history: orality, scroll, codex, manuscript, print, the standardized page, mass translation, database and hypertext, search, the smartphone, and generative AI.
Each technology changes what a person must spend for a meaningful encounter with text to happen, and each relocates that work, often somewhere hidden. The words of Berakhot 2a stay fixed while the activity of reaching them shifts enormously, from a teacher's memory, to a manuscript you travelled to see, to a Vilna Shas, to Sefaria, to a chatbot. That shifting activity is the subject of the book.
The Talmud tells of Rabbi Meir arriving before Purim with no Megillah available. He writes Esther from memory and reads from his own copy, an act permitted only as an emergency, since a biblical text is normally copied from a written exemplar. The rabbis here keep apart things we tend to merge: holding correct information, knowing it, and producing a valid textual object.
Rabbi Meir carries the text within himself and can therefore regenerate the artifact. Our situation runs the other way: we increasingly generate the artifact while carrying less of the text. The project reads this as a change in where the work lives and sets out to trace where it has gone.
Every transition is examined with a single question: what else had the old labor been doing?
Some friction was simply the price of inadequate technology, such as a rare book beyond a poor student's reach or a clumsy index, and its removal widens Jewish learning. Other friction was quietly shaping people and communities. Sorting one kind from the other is historical work, and the project holds the answer open until the evidence arrives.
The sefer Torah keeps production costly. Jewish practice has far cheaper ways to reproduce Hebrew letters and deliberately sets them aside for this one object. It treats access to semantic content and instantiation of a meaningful object as separate categories, categories that computing tends to fuse. The scroll has even grown more sacred as handwriting lost its informational role, which shows a medium gaining ritual weight after its practical job passes elsewhere.
The Talmud page keeps navigation costly. Base text sits at the center with Rashi beside it, Tosafot opposite, and cross-references and later voices at the margins. What the page offers is a structured history of interpretation, so a reader reaches any answer by passing through the relationships that produced it. The formula "Rabbi X said in the name of Rabbi Y" performs the same work at the scale of a sentence, making attribution a ritualized form of epistemic labor.
Together these two objects mark the rough end of the smoothness continuum, and every later medium can be placed against them.
McLuhan's tetrad asks four simultaneous questions of any medium: what it enhances, what it obsolesces (pushes into the background), what it retrieves from an earlier environment, and what it reverses into when pushed to its limit. Read the four together as one moving figure.
Levinson's tetrad wheel runs tetrads in sequence. A successor medium passes the wheel test when the predecessor's reversal becomes its enhancement (D₁→A₂), the predecessor's enhancement becomes obsolesced ground (A₁→B₂), and the predecessor's obsolescence returns as retrieval (B₁→C₂), while the successor's own reversal (D₂) is genuinely new. The project's contribution is to test and extend this mechanism through Jewish media, formation, ritual validity, communal scaffolding, and visible genealogy.
Chiasmus with caution. A crisp AB→BA sentence can point toward a reversal: Jews built technologies to remember texts; technologies now remember texts for Jews. The project calls such patterns meta-chiasms and earns them transition by transition through local, historically grounded wheel tests.
Chronology as hypothesis. The provisional sequence runs from oral tradition to generative AI, and the forms overlap and persist. Jewish media history may look more like a braided spiral, with older figures remaining deliberately present inside newer environments.
At the formation scale, ask what capacities and relationships the old labor produced in an individual. At the civilizational scale, ask what forms of peoplehood, authority, coordination, and adaptation that labor sustained. A friction can be accidental for a person yet embedded in an institution, and an efficiency can widen access while changing who constitutes the shared textual world.
Midrash is a relationship between an inherited text and new meaning in which the source stays preserved and interpretation grows around it. A difficulty generates more text; a contradiction stays productive; a strange word sustains generations of attention. That relationship is itself a media form, and the Talmud page performs it physically. Hence the title, which is meant literally.
Generative AI arrives last, as the culminating case, so that readers meet it already knowing how every earlier convenience reorganized Jewish textual practice. Its particular move: search answers where is the thing? while generative AI answers what does the thing mean? Interpretation itself becomes infrastructure.
The provisional AI tetrad takes enhancement seriously, including a teenager with no Jewish schooling questioning the corpus conversationally, minority traditions becoming discoverable, the beginner free to ask the embarrassing question, and the retrieval of a dialogic, oral mode of asking and objecting. Corpus navigation as a precondition for interpretation moves into the background. At its limit, interpretation becomes so abundant that it stops serving as evidence of learning and buries the stable text it was meant to illuminate.
Here Jewish law becomes a resource. It already holds many cases where identical-looking outputs differ because their histories of production differ: the scroll, the shofar blast, the witnessed act, the intention behind a mitzvah.
Medium is Midrash investigates how successive technologies of Jewish text redistribute the labor required to preserve, access, navigate, interpret, transmit, and instantiate Torah—and how those redistributions change the kinds of relationships Jews can have with texts, teachers, communities, memory, and interpretation.
