In 1865, the British Parliament passed the Locomotive Act. It required any self-propelled vehicle on a public road to be preceded by a person walking in front of it, carrying a red flag.

Speed limit: 4 mph on country roads. 2 mph in towns.

Parliament literally made cars walk.

The law stayed on the books for thirty-one years. By the time they repealed it in 1896, Karl Benz had already built the first production automobile, France was hosting motor races, and Britain’s early auto industry had been stunted for a generation.

The people who passed this law were solving a real problem. Roads were built for horses. The economy ran on horses. Horses were predictable. A horse would stop if it saw an obstacle. A car wouldn’t.

People were genuinely dying. The flag made sense if your model of transportation was a horse with an engine bolted on.

This is what humans do. Every time. A new thing appears. The majority mocks it, fears it, or passes legislation requiring it to walk at 2 mph. A minority worships it as salvation.

Both groups are wrong. The reality takes about fifteen years to become obvious, and by then everyone pretends they saw it coming.

The Parade

In the 1490s, Johannes Trithemius, a Benedictine abbot, wrote an entire book arguing that the printing press would destroy knowledge. His reasoning was that monks copying manuscripts by hand was a spiritual discipline, and mechanical reproduction stripped the sacred from the act of transmission (echos of Thoth/Hermes? Yeah. Different tech, same idea.) The press was a shortcut, and shortcuts produced shallow minds.

He had the book printed.

Four centuries later, Western Union’s internal committee evaluated Alexander Graham Bell’s patent and passed. Their assessment: “This ‘telephone’ has too many shortcomings to be seriously considered as a means of communication.” The committee understood telegraphy perfectly. They understood the telephone as a worse telegraph, which is what it was, right up until it became something else entirely.

In 2007, Steve Ballmer, CEO of Microsoft, laughed on camera about the iPhone. “$500? Fully subsidized? With a plan? That is the most expensive phone in the world. And it doesn’t appeal to business customers because it doesn’t have a keyboard.” He understood the smartphone market as it existed that morning. By that afternoon, the market was a different shape. Microsoft’s smartphone division eventually went to zero. Apple’s market cap became the largest on earth.

The pattern is clean. Specific, confident predictions of failure, made by people who understood the current technology perfectly and the next technology as a broken version of the current one.

Trithemius saw the press as a monastery without discipline. Western Union saw the telephone as a telegraph without reliability. Ballmer saw the iPhone as a BlackBerry without a keyboard. Each of them measured the new thing against the old thing and found it lacking, which was accurate, and also completely beside the point.

The Tide

Here’s where it gets interesting. And where it stops being funny.

The instinct to reject unfamiliar technology feels like a choice. It feels like skepticism, like critical thinking, like the reasonable caution of an experienced mind.

It’s biology.

Fluid intelligence, the kind you use for novel problem-solving and adapting to unfamiliar systems, peaks in your twenties and declines steadily after. Crystallized intelligence, accumulated knowledge and expertise, keeps climbing into your sixties. These two curves cross somewhere in middle age.

So you get progressively better at understanding the world as it was when you learned it. And progressively less equipped for the world as it’s becoming.

The technology you encounter between roughly ten and twenty-five feels native. Everything after that requires effort that increases with each passing year. And there’s a quiet moment, different for everyone, where you stop learning the new system and start finding workarounds that let you keep using the old one.

This is how brains work. It happens to everyone. It will happen to you, if it hasn’t started already. The technology you find intuitive right now will feel as alien to your grandkids as a rotary phone feels to a teenager.

And this is okay. Individuals losing fluency with new technology is the natural tide of a life. It recedes. The water ends up somewhere else.

It only becomes a problem when the people who’ve stopped adapting are the ones setting the pace for everyone else.

The Seniority Trap

In 2006, Senator Ted Stevens of Alaska stood on the Senate floor and described the internet. He was 82 years old and the chairman of the Commerce Committee, the committee responsible for regulating it.

“The internet is not a big truck,” he explained. “It’s a series of tubes.”

He also described waiting overnight for an email, attributing the delay to congestion. The speech became one of the internet’s most enduring jokes. It was also the voice of internet regulation at the time.

In 2018, during hearings meant to determine the future of social media regulation, Senator Orrin Hatch asked Mark Zuckerberg how Facebook makes money if users don’t pay for it. Hatch was 84.

Zuckerberg paused. “Senator, we run ads.”

These moments look like comedy. They’re structural. The natural process of calcification intersected with institutional power, and this is what it produced. Stevens and Hatch were typical. The seniority system that placed them in those chairs is designed to reward longevity, which means the people with the most authority over new systems are, by structural design, the people who came of age furthest from them.

The Soviet Politburo in its final years had an average member age of 70. Three leaders died in office in three years. Konstantin Chernenko took power at 72 and was so diminished they affixed a facsimile of his signature to official documents because he couldn’t hold a pen.

The Soviet Union never developed a personal computer industry. Its aging leadership chose to pirate Western designs. The country that launched the first satellite and put the first human in space couldn’t build a consumer PC. The engineering talent was there. The decision-makers were the bottleneck, because they couldn’t see what personal computing was for.

In each case the institution’s seniority structure guaranteed that the people with the least fluency in new technology held the most power over its future. The gap between the decision-makers and the decisions they were making widened until something broke.

The pattern is politically indifferent. It doesn’t care about ideology, nationality, or system of government. It cares about the age of the people holding the levers and the speed at which the levers are changing.

The King Who Lived Forever

In 1726, Jonathan Swift invented the Struldbrugs: the immortals of Luggnagg. They keep aging forever, losing memory, sight, and hearing until they can’t understand the language spoken by subsequent generations. The country declares them legally dead at eighty while their bodies keep going.

Swift meant it as horror. A life that continues long past the point where it can adapt to the world it’s living in.

Every reader of that passage assumes they’d be the exception. They’d stay sharp. They’d keep learning. They’d be the immortal who still understands the language.

Swift’s point is that you wouldn’t. Nobody would. The architecture of the mind guarantees it. And the Struldbrugs don’t know they’ve fallen behind, because the falling happens so gradually that each day feels like continuity.

The question Swift was really asking was about what happens when the natural endpoint of influence is removed. When the thing that normally forces a transfer of power, a funeral, stops happening. The Struldbrugs are declared legally dead at eighty because the society around them figured out that biological life and functional life aren’t the same thing, and that the gap between them grows in only one direction.

Swift wrote it as satire about mortality. It reads now like a case study in institutional design.

The Flag-Bearers

The Red Flag Act was repealed in 1896. Thirty-one years of walking.

The people who passed it were managing real risk with the only tools they had, which was experience and precedent. The caution was legitimate. The danger was real. And the cost of that caution, invisible at first, compounded quietly for three decades while France and Germany built the industries that would define the next century.

This is the hard part, the part that resists easy answers. Some flags need carrying. Some caution is warranted. New technologies do kill people, do destroy livelihoods, do create problems that the enthusiasts refuse to see. The abbot worried about shallow minds wasn’t entirely wrong. The senator who didn’t understand the internet was still asking a question that needed asking, even if he wasn’t equipped to understand the answer.

The problem is specific. It’s the structural guarantee that the people setting the speed will be the ones who learned to walk first. It happens in every system that rewards seniority. It happens in every culture that conflates experience with foresight. It happens gradually, invisibly, the way all tides happen, and by the time the gap is obvious, a generation of opportunity has already passed.

The flag-bearer looks behind and sees the machine gaining. Looks ahead and sees the road they’ve walked their whole life. They know this road. They know its ditches, its blind curves, its history. Their caution is earned. And the machine behind them is still moving at 2 mph, because that’s the speed they set, and nobody has built a system that knows when to take the flag out of their hands.

Nobody ever has. The flag gets carried until something forces the transfer: a crisis, a collapse, a funeral, a parliament that finally votes thirty-one years too late.

The question has never been whether the flag-bearers will be there. They will always be there. You’ll be one yourself someday, walking in front of a machine you don’t recognize, holding a flag for reasons you believe are sound.

The question is whether we can build systems that account for this. Systems that respect the flag-bearer’s knowledge without letting it set the speed. Systems that transfer the flag before the crisis forces it.

That would be new. In the entire history of institutions and technology, that would be genuinely new.

We haven’t done it yet.
