AGI is Here. Anthropic Just Proved It.

Anthropic published a report called "When AI builds itself," revealing that more than 80% of the code it ships is now written by its own model, Claude. Nate reads it as evidence that AGI is not a far-off future thing we are all waiting for, it is already here by the definition that actually matters. He walks through what AGI really means, why everyone gets stuck arguing about the word general, the key things he took from the report, and what he thinks it means for society.

• "More than 80% of the code that Anthropic ships is now written by their own AI, Claude," per a report they just dropped called "When AI builds itself."
• His thesis: "by the definition that actually matters, AGI is already here," not "this far off future thing that we're all just kind of waiting for."
• He reframes the usual definition fight: "everyone gets stuck arguing about that middle word, general."
• He treats the report as Anthropic "pull[ing] back the curtain on what's actually going on inside of their own business," not marketing.
• The framing itself, "When AI builds itself," points at the loop: the model now writes most of the code that improves the model.
