30年前と今を比べると、なかなか衝撃。 ・消費税　3% → 10% ・ドル円　102円 → 162円 ・ビッグマック　210円 → 500円 ・ディズニー　4,800円 → 10,900円 ・国民年金　11,100円 → 16,980円 ・国民負担率　36.3% → 46.8% ・平均年収　470万円 → 420万円 ・国会議員報酬　1,610万円 → 2,156万円 電気代も、ガソリン代も、家賃も、食費も上がった。この30年で豊かになったのは、財布の中身じゃなくて支払い項目だけだよ。まったく。

A Japanese engineer invented the QR code for one job, tracking car parts on a Toyota line, then his company chose to give the patent away for free, which is the only reason it ended up on every restaurant table on Earth. His name is Masahiro Hara. The company was Denso Wave, a parts supplier owned by Toyota. In 1992 the problem landed on his desk, and it was not glamorous. Workers on the factory floor were drowning. Every car part had a barcode, but a barcode can only hold about twenty characters, so to track one component they had to stick five or ten barcodes on it. A worker would stand there scanning a single part ten times in a row. Some of them were scanning close to a thousand barcodes a day. The job had stopped being about building cars and turned into pointing a scanner at stickers all day long. And there was a second problem nobody upstairs cared about. This was a factory. Oil got on everything. A smudge of grease across a barcode and the whole thing became unreadable, and the line stopped. Hara was asked to make the scanner faster. He looked at it for a while and realized the scanner was not the problem. The barcode itself was the ceiling. A line of black bars can only hold information going one direction, left to right. He decided to build something that held information in two directions, up and down as well as across, so it could store hundreds of times more in the same little square. Then came the part that sounds made up but is not. Hara played Go on his lunch breaks, the old board game with black and white stones sitting on a grid. He was staring at the board one day and it clicked. The grid of black and white stones was already a way to store information in two directions. That was the shape of his code. But building the code was the easy half. The hard problem was speed, because the whole point was to be fast, and a scanner wastes most of its time just trying to figure out where the code is and which way it is turned. The fix came to him on a train. He was looking out the window at buildings, and one building stood out from all the others because of its shape against the sky. That was the idea. He put three little square targets in three corners of the code. The moment a scanner sees those three squares, it knows instantly where the code is and how it is rotated, even upside down, even at an angle. Now here is the detail that shows how far he was willing to go. Those three corner squares only work if nothing else on the page looks like them. If a magazine ad or a cardboard box happened to have the same black and white pattern nearby, the scanner would get confused and grab the wrong thing. So Hara and his tiny two-person team went and surveyed printed material. Magazines. Flyers. Cardboard boxes. Piles of it, for days, reducing every picture down to its ratio of black to white area, hunting for the one ratio that almost never shows up in print anywhere. They found it. One to one to three to one to one. That exact rhythm of black and white is baked into every corner square of every QR code on Earth, and it is there because it is the pattern the printed world almost never produces by accident. Then he solved the oil. He built the code so it carries a backup of its own information, spread mathematically across the whole square. You can tear off, smudge, or scratch out up to thirty percent of a QR code and it still scans perfectly, because the code rebuilds the missing piece from the copy it kept of itself. A worker could get grease on a third of the label and the line would keep moving. This is the same math that lets a scratched CD still play and lets a spacecraft send data back across the solar system without asking to repeat itself. He finished in 1994. He named it Quick Response, after what it does for the person using it, not after what it is. And then Denso made the decision that actually mattered. They held the patent. They could have charged a fee on every single scan, and given how many billions happen now, that would have made someone unimaginably rich. Instead they announced they would not enforce their rights to collect royalties, and they published the specification openly so anyone could use it. Hara later said it was not even a big argument inside the company. That one choice is the whole story. A code that costs nothing to use is a code everyone builds on. Airlines put it on tickets. Phone makers built readers into cameras. Then a pandemic hit and the world needed a way to hand someone information without touching anything, and the free little square that a Toyota engineer built for greasy factory workers was suddenly on every menu, every payment, every door. Hara still works there. He has said, more than once, that he never imagined it would spread this far, and that the part he is proudest of is that it got used to keep people safe. The man built it to survive oil on a factory floor. It ended up surviving everything else too. You have scanned his work a hundred times this year. Now you know whose it was.

デザイナーじゃない人がデザイナーに意図や雰囲気を伝えるためにどうしていいか分からず生成AIを使って説明を試みることに対してデザイナーたちが「軽視してる」「舐めてる」と猛反発する、というよく見る光景。我々もデザインを扱っており同じように顧客から提示される可能性もあるため気持ちは分からなくもないが、こういう対立構造を作ると「このデザイナーと仕事するの面倒くさい」と思われるだけで悪手だと思うけどな。不快だ、もっと我々に気を使え、と自分のお気持ちを満たすことより、相手がなぜそうしてきたのか、何をしたがってそうしてるのかの意図を把握し、余計なノイズは軽くいなしながらミスコミュニケーションを解消してあるべき方向に導くのもデザイナーの手腕だと私は思うのだけど。
