Origins of the Y2K Scare

The Y2K scare, also known as the Millennium Bug or Y2K Bug, had people worldwide bracing for technological chaos as the year 2000 approached. The fear stemmed from the way computer systems recorded dates using only the last two digits of the year, meaning 2000 would be indistinguishable from 1900. An article in TIME Magazine in 1998 explained the glitch thusly:

“The bug at the center of the Year 2000 mess is fairly simple. In what’s proving to be a ludicrously shortsighted shortcut, many system programmers set aside only two digits to denote the year in dates, as in 06/15/98 rather than 06/15/1998. Trouble is, when the computer’s clock strikes 2000, the math can get screwy. Date-based equations like 98 – 97 = 1 become 00 – 97 = -97. That can prompt some computers to do the wrong thing and stop others from doing anything at all.”

This seemingly minor glitch was expected to wreak havoc, disrupting everything from financial systems to utilities and anything that contained computer chips, including elevators and medical equipment. Here’s how Vanity Fair Magazine described the potential Y2K Bug problems in its January 1999 edition:

The nightmare scenario goes like this: It is an instant past midnight, January 1, 2000, and suddenly, nothing works. Not ATM’s, which have stopped dispensing cash; not credit cards, which are being rejected; not VCRs, which now really are impossible to program. The power in some cities isn’t working, either, and that means no heat, lights, or coffee in the morning, not to mention no televisions, stereos, or phones, which—even in places with power—aren’t working, either. Bank vaults and prison gates have swung open; so have valves on sewer lines. The 911 service isn’t functioning, but fire trucks are on the prowl (though the blaze had better be no higher than the second floor, since their ladders won’t lift). People in elevators are trapped, and those with electronic hotel or office keys can’t get anywhere, either. Hospitals have shut down because their ventilators and X-ray machines won’t work—and, in any case, it’s now impossible to bill the H.M.O.

Traffic is a mess, since no streetlights are working. Trains are running, but their control switches aren’t, which is bad news for supermarkets, utilities, car dealers, and international trade, which can’t move by ship either. Only the brave or foolhardy are getting on airplanes—but with so many countries degenerating into riots and revolution, it’s wiser to stay at home anyway. There are no newspapers to read or movies to go to or welfare checks to cash. Meantime, retirees are opening letters saying that their pensions have been canceled because they are minus-23 years old. Many banks and small businesses have gone bust, and it will be weeks—if ever—before the mess that is the broker’s statement is sorted out.

Given dire predictions of the effects of the Y2K Bug, many people were concerned about what would happen as 12/31/1999 flipped to 1/1/2000.

Life on 1/1/2000

My wife and I spent New Year’s Eve 1999 at a party at a neighbor’s house. I remember the trepidation and then the sense of relief as the clock moved past midnight and nothing happened. News reports in the days after we entered the new millennium reported only scant issues due to the Y2K Bug. We were shocked.

The Y2K Bug did create some issues, but they were minor. Things like:

• The system for collecting small plane flight information failed in Japan (but no planes fell out of the sky).
• Australian bus ticket machines failed.
• The Federal Reserve Bank of Chicago couldn’t transfer $700,000 in tax payments; however, it made the transfer successfully the next day.
• Seven nuclear reactors in the US had minor glitches relating to plant support.
• South Korea summoned 170 people to court on the 4th January 1900.
• Most worrisome, a customer at a New York State video rental had a bill for $91,250. This was the cost of renting “The General’s Daughter” (the film, not an actual general’s daughter) for 100 years. LOL.
• Etc.

But there were no major problems. Power plants continued to work, planes continued to fly, elevators continued to go up and down, and ATM machines continued to spit out cash.

Why Wasn’t Y2K a Problem?

There are two competing stories about why Y2K ended up not being a problem.

One story is that the Y2K bug was overhyped by the media, governments, and even consultants and programmers who wanted to be paid to fix a non-existent problem. In short, if we had done nothing, we’d have had the same result.

The other story is that Y2K wasn’t a problem because of the massive global effort to fix it in the years leading up to 2000. This reminds me of a scene in the excellent movie “Kingsman: The Secret Service.” Kingsman is an independent intelligence agency that thwarts terrorist attacks and undermines rogue governments and eccentric evil billionaires. A senior agent in Kingsman, Harry Hart (played by Colin Firth), has newspaper front pages with unremarkable headlines displayed on his office wall. When queried by aspiring agent Eggsy Unwin about the newspapers, Harry explains that the newspaper covers are for the day after his missions, where he foiled potential world-changing disasters. Instead of a horrible international event dominating the news, due to his efforts “celebrity nonsense” dominated the headlines instead.

Experts claim that Y2K wasn’t a problem for the same reason there were banal headlines the day after Harry Hart’s missions: preparation. While people were panicking, joining doomsday cults, and hoarding food and water in the years leading up to 2000, behind the scenes, there was an army of people working on fixing the problem. Worldwide, an estimated $300 billion – $500 billion was spent to fix the Y2K Bug ($650 billion – $1 trillion in 2024 dollars), with nearly half being spent in the U.S. Those who worked in Y2K-compliance efforts claim Y2K wasn’t a problem due to the massive efforts of businesses and governments.

“The Y2K crisis didn’t happen precisely because people started preparing for it over a decade in advance. And the general public, who was busy stocking up on supplies and stuff, just didn’t have a sense that the programmers were on the job,” said Paul Saffo, a futurist and adjunct professor at Stanford University.

Which story is correct?

Personally, I side with the experts who claim that the problem was solved by preparation. I don’t think private corporations would have spent so much money if they hadn’t been sure that the problem was real. This narrative provides hope for humanity’s ability to fix other big problems (I’m looking at you, global warming).

But I do have a sliver of doubt because it seems a stretch to think that all the code worldwide with the Y2K Bug was fixed, and yet there were no major problems as the clock struck 2000. Plus, some countries, notably Russia, spent way less than the U.S. to fix the Y2K Bug and didn’t experience major issues.
