Man, I just started learning markdown! I can't keep up! ICM in HTML? "It started with Thariq Shipar, Engineering Lead on Claude Code at Anthropic. On May 8, he tweeted: โHTML is the new markdown. Iโve stopped writing markdown files for almost everything.โ His argument: when AI writes the content, Markdownโs โeasy to writeโ advantage becomes less relevant. HTML gives you richer layouts, interactivity, and visual hierarchy. Why he thinks HTML wins: Shipar backed it up with a companion site showing 9 categories where HTML artifacts beat Markdown: - Interactive dashboards - Styled code reviews - Inline SVG illustrations - Arrow-key presentations - Collapsible explainers Things that are impossible in a flat .md file become trivial when AI generates HTML. But there was pushback. Developer Kutis Redux published a direct rebuttal: โThe Unreasonable Ineffectiveness of HTMLโ His argument: the switch to HTML creates visual gloss at the expense of source readability, security, ecosystem compatibility, and reviewability. His core point: HTMLโs raw source is hostile to human eyes. Markdown stays readable whether rendered or not, which matters when youโre reviewing what an AI just wrote. Then Andrej Karpathy weighed in and went bigger. He called it an evolution: raw text โ Markdown โ HTML โ neural interfaces His advice: Add โstructure your response as HTMLโ to your prompts. He confirmed: โIt works really well.โ The endgame? AI outputs will not be static documents at all. Theyโll be interactive simulations."
