AI Unverifiable I could not verify this to a high-confidence, verbatim standard. The original X URL was not retrievable through the browser tool, so I could not inspect the source post directly. Multiple third-party mirror/search snippets do show the exact quoted wording attributed to “Sebastian Mallaby @scmallaby,” and they align with a New York Times op-ed by Mallaby published on April 13, 2026 about abandoning chip-export controls and pursuing AI-safety cooperation with China.
