Governed Persistence: Shared Computers, Named Agents, and Ship Gates
Three products shipped in 2026 that put a standing computer behind a named agent, and they answered the question that matters in three different ways. xAI's Grok Bot, released in early beta on Aug. 11, 2026 and opened to enterprises on Sep. 3, gives each member of a team one persistent Linux virtual machine shared by every Bot that member creates, holding files, browser cookies and sessions, command-line credentials, and installed connectors across weeks of work. Cursor's Cloud Agents take the opposite position: each run gets an isolated machine, clones from hosted git, signs its commits with a hardware-backed key, and returns a pull request rather than a patch in a chat window. That first opposition is not between competitors. SpaceX agreed to buy Cursor's parent in Jun. 2026 and closed the purchase in Aug. 2026, so both products now ship from one company holding both answers at once. Meta's Muse, released on Sep. 8, 2026, keeps the standing computer and moves the credential off it: a separate process on the same machine controls every outbound request and swaps in secrets the model only ever holds as placeholders. All three are environments that outlive the turn, and the question they force is who holds the authority to ship what those environments produce.
