In the first week of December 2025, a Google principal engineer sat down with Claude Code and described, in plain English, a problem her team had just spent the past year trying to solve.
Three paragraphs. A brief description of the problem with “no real details,” she said, because she couldn’t share anything proprietary, especially not on a competitor’s platform.

She posted about it publicly.
“I am not joking,” she wrote on X, “and this isn’t funny.”
