Karpathy says Markdown is just the beginning.
Man, I just started learning markdown! I can't keep up! WAT in HTML?
"It started with Thariq Shipar, Engineering Lead on Claude Code at Anthropic.
On May 8, he tweeted:
“HTML is the new markdown. I’ve stopped writing markdown files for almost everything.”
His argument: when AI writes the content, Markdown’s “easy to write” 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:
“The Unreasonable Ineffectiveness of HTML”
His argument: the switch to HTML creates visual gloss at the expense of source readability, security, ecosystem compatibility, and reviewability.
His core point:
HTML’s raw source is hostile to human eyes.
Markdown stays readable whether rendered or not, which matters when you’re reviewing what an AI just wrote.
Then Andrej Karpathy weighed in and went bigger.
He called it an evolution:
raw text → Markdown → HTML → neural interfaces
His advice:
Add “structure your response as HTML” to your prompts.
He confirmed:
“It works really well.”
The endgame?
AI outputs will not be static documents at all.
They’ll be interactive simulations."
