Microsoft moves Copilot Cowork from preview to general availability

Before this release, most builders treated Copilot features as optional experiments that could be ignored without consequence. The output was often incomplete or unsafe, so the cautious approach was to keep it at arm's length. General availability changes the expectation inside organisations. Colleagues and managers now assume the assistant is ready for real work, which pressures makers to use it even when they cannot yet judge whether the generated formulas, data calls, or approval flows will survive actual list sizes and permissions.
