AC/DC: The Savage Tale of the First Standards War

The War Before the War

Most people locate the origins of modern technological competition somewhere in the twentieth century — the space race, the VHS-Betamax showdown, the browser wars. Tom McNichol’s account of the Edison-Westinghouse current wars forces a correction. The foundational drama of competing technical standards, with all its propaganda, financial terror, and personal vendetta, played out in the 1880s and 1890s, before most of the infrastructure of modern life existed at all. The argument embedded in this book is not simply that history repeats itself. It is something sharper: that the form of standards warfare was established in this single brutal episode, and every subsequent technology battle has been a variation on the same score.

What makes this necessary reading is not the history of electricity per se. It is the anatomy of how a dominant incumbent responds to a genuinely superior challenger — and how that response, driven by ego and commercial fear rather than engineering judgment, can delay progress, harm people, and ultimately still fail.

Edison’s Trap

Edison was not a fool, and McNichol does not treat him as one. He was arguably the most gifted practical inventor of his era, and his direct-current system was a legitimate engineering achievement. But DC carried a fatal limitation: voltage drops made transmission over distances greater than roughly a mile economically prohibitive. A city the size of New York required dozens of generating stations. Alternating current, as developed by Tesla and commercialized by Westinghouse, could be stepped up and transmitted over hundreds of miles, then stepped down for local use. The physics were simply better.

Edison knew this. That is the crucial and somewhat tragic detail. He understood the engineering case against his own system. His response was not to adapt but to attack — to wage a public campaign portraying AC as inherently lethal, funding demonstrations in which animals were publicly electrocuted with alternating current, and ultimately lobbying for AC to be used in the electric chair, so that death by electricity would become synonymous in the public mind with the Westinghouse system. This is one of the more chilling episodes in the book: a man of genuine brilliance deploying his credibility as a scientist to perform essentially theatrical executions, hoping fear would substitute for physics.

The insight here is not merely biographical. It illustrates a structural pathology in any standards competition: the incumbent’s sunk costs are not just financial but psychological. Edison had staked his identity on DC. Acknowledging AC’s superiority would have required a kind of intellectual humility that his character, shaped by decades of being right through sheer will, apparently could not accommodate.

Standards as Social Constructs, With Real Consequences

What McNichol captures well is that a technical standard is never purely technical. It is a social agreement about how a technology will be developed, financed, taught, and regulated. Once a standard achieves critical mass, it becomes self-reinforcing in ways that have nothing to do with engineering merit. Edison’s DC infrastructure, already installed in parts of Manhattan, created constituencies — investors, utility workers, equipment manufacturers — who had reasons independent of physics to prefer its survival.

This connects directly to what economists call path dependence, and it illuminates why technically inferior standards sometimes persist for decades. The familiar QWERTY keyboard case has been debated to exhaustion, but the current war is a cleaner example because the technical differential was so unambiguous. AC won not because the market instantly recognized truth but because Westinghouse was willing to take on enormous financial risk, Tesla was willing to work for almost nothing, and the 1893 Chicago World’s Fair gave AC a stage large enough to demonstrate its superiority to millions of people simultaneously. Standards, in other words, are won through demonstration events as much as through technical merit — a lesson Silicon Valley has absorbed and replayed endlessly.

Tesla in the Margins

The figure of Tesla haunts the book without quite dominating it, and that restraint is wise. Tesla was the engineering genius who made AC transmission practical, but he was constitutionally unsuited to the commercial warfare the situation required. He was uninterested in financial self-protection, gave up his royalty rights under pressure, and ultimately died broke while his patents underpinned an entire civilization. McNichol does not sentimentalize this. Tesla’s fate was partly structural — inventors in rapidly commercializing industries are routinely stripped of the value they create — but it was also partly the consequence of his own indifference to the mechanisms of economic survival.

The adjacent field this most directly illuminates is the economics of innovation: specifically, the well-documented gap between who creates value and who captures it. Tesla is an extreme case, but the pattern recurs in pharmaceutical chemistry, in software, in materials science.

Why It Still Matters

We are living through multiple simultaneous standards wars right now — in electric vehicle charging infrastructure, in wireless communication protocols, in AI model interfaces. The specific technologies differ; the underlying logic does not. An incumbent with installed base and political access will use every available tool, including fear, misinformation, and regulatory capture, to slow a superior challenger. The challenger’s task is not simply to be better but to manufacture a moment of undeniable public demonstration that breaks the incumbent’s narrative hold.

McNichol’s book is ultimately a case study in how progress actually happens — not smoothly, not rationally, but through conflict that is as much theatrical as technical. Understanding that dynamic is not cynicism. It is preparation.
