iOS 27 drops global Apple Intelligence toggle, switches to per-feature opt-out

KEY FACTS

iOS 27 no longer offers a system-level Apple Intelligence master switch, forcing users to turn off each AI feature individually.
Supported devices are iPhone 15 Pro and newer or iPhone 16 and newer, while iOS 26 still keeps a one-tap off switch.
Users can disable Siri in Settings and switch back to the legacy Siri Classic.
AI summaries for Messages, Mail, and notifications can each be turned off in their respective settings.
Writing Tools and image generation must be blocked through Screen Time privacy restrictions.

PHYSIX OBSERVATION

Apple has split the AI switch from a single kill switch into a dozen granular toggles. On the surface it hands users control, but in reality it shifts the cost of compliance and experience onto them. For people who dislike AI, simply finding all these switches is itself a burden; for the industry, it signals that system-level AI is moving from an optional feature to a default foundation, and turning it off cleanly will only get harder.
