Nearly every bit of the high-tech world, from the most cutting-edge AI systems at the biggest companies, to the casual scraps of code cobbled together by college students, is annotated and described by the same, simple plain text format. Whether you’re trying to give complex instructions to ChatGPT, or you want to be able to exchange a grocery list in Apple Notes or copy someone’s homework in Google Docs, that same format will do the trick. The wild part is, the format wasn’t created by a conglomerate of tech tycoons, it was created by a curmudgeonly guy with a kind heart who right this minute is probably rewatching a Kubrick film while cheering for an absolutely indefensible sports team.

But it’s worth understanding how these simple little text files were born, not just because I get to brag about how generous and clever my friends are, but also because it reminds us of how the Internet really works: smart people think of good things that are crazy enough that they just might work, and then they give them away, over and over, until they slowly take over the world and make things better for everyone.
