By the 1760s insurance had its machinery. There was pooling, the priced premium, loss prevention, mutual ownership, and the math to hold it together. What it had not met was the machine.

The factory and the grand bargain

Industry made dangers that had never existed. Factories had unguarded belts and boilers, and they maimed workers at a scale nobody had seen. One accident could ruin a wage earner and his family in an afternoon.

Workers, including children, on an industrial factory floor beside unguarded belt-driven machinery, the kind of workplace whose accidents gave rise to workers' compensation insurance
An industrial factory floor and its unguarded machinery. Injuries at this scale forced a new bargain: guaranteed compensation in place of the courtroom.

The law offered them almost nothing. If a co-worker's mistake played a part, the employer often walked free. If the worker knew the job was dangerous and did it anyway, that counted as consent.

Germany answered first. In the 1880s, under Bismarck, the state built required accident insurance for workers. The trade is called the grand bargain. Workers gave up the right to sue over most injuries at work. In exchange they got paid without having to prove fault. A crushed hand was paid for either way.

The United States followed a generation later, state by state. Wisconsin passed the first law to survive a court challenge in 1911. Certainty replaced the courtroom lottery, and a predictable cost is what an insurance market is built to carry.

A machine in every driveway

Then came a machine that could kill a stranger, and people took it home.

Older risks mostly pointed inward. A house fire threatened the owner. A car threatened everyone else: a pedestrian, a child, the family in the oncoming lane. None of them chose how carefully the driver drove.

This is where liability enters. Liability is legal responsibility for harm you cause someone else. Liability insurance pays when you are found responsible, covering the damages and the cost of defending you.

The first American auto liability policies appeared in 1897 and 1898. As the roads filled, that novelty became a mass product, then a legal requirement. If your machine harms a stranger, there should be money behind you to make that stranger whole.

An early automobile from the 1900s to 1910s on a public road, the machine whose danger pointed outward at strangers and made liability insurance a mass product

The liability century

The century kept widening who could be blamed, and cover kept pace. Product liability law held makers answerable for harm done by things they made, years after a sale. Directors and officers cover protected company leaders from ruin over a business decision.

One pattern runs through all of it. Insurance answers to how a society decides who is to blame. Each time the law named a new harm, cover grew up around that decision.

Cyber was the rehearsal

From the late 1990s insurers wrote cover for a risk with no physical form. No burning building, no wrecked car. Instead a data breach, a network failure, later ransomware.

Cyber was hard for three reasons that will sound familiar. It was invisible, so no underwriter could walk the property the way a fire inspector walked a warehouse. It changed faster than the policies written to cover it. And one flaw in widely used software could hit thousands of firms at once, which breaks the spreading that makes pooling work.

Insurers learned three lessons and are using every one on AI. Demand security controls as a condition of cover. Watch for silent exposure, where a new loss gets covered by accident under an old policy never priced for it. And reprice often, sometimes cutting a risk out with an exclusion.

The AI chapter

When generative AI reached everyday business use around 2023, it opened a gap almost overnight. A model that drafts copy, screens applicants or writes code can also defame someone, infringe a copyright, discriminate, or fail in a way that costs real money. The policies firms carried were written long before anyone imagined that.

The industry calls the result silent AI risk. Nobody can say whether a standard liability policy would pay for an AI loss, because none were designed with one in mind. That is dangerous for both sides. Buyers cannot be sure they are covered. Insurers cannot be sure how much AI risk they have built up.

The market moved two ways at once. Insurers began cutting AI out of standard policies so it would stop being covered by accident. Verisk's generative AI endorsements started attaching to general liability renewals from 1 January 2026. Dedicated policies also arrived that name the risk on purpose. Armilla launched a standalone AI liability policy at Lloyd's in April 2025, built to pay when a system underperforms or produces damaging errors.

Where the line runs next

An affirmative AI policy asks what Halley's tables and Franklin's inspectors asked. How likely is this to fail? What would that failure cost? What controls can you put in place before we carry the rest?

Expect pricing to sharpen as real losses pile up. Expect cover to arrive with requirements attached, exactly as fire marks and house inspections once were. The open question is a shared failure: thousands of firms relying on one model, all failing together. That would be the AI version of the Great Fire.

The technology is new. The instinct behind the cover is close to four thousand years old.
