Google Chrome silently downloads Gemini Nano

This is a trust problem disguised as a convenience feature: on-device AI can be useful, but silently consuming storage and bandwidth makes Chrome look like it is commandeering user hardware for Google’s roadmap.

• –Google’s own docs say Gemini Nano model management happens in the background, so the mechanism is deliberate rather than a bug.
• –The real problem is consent and control: users do not get a normal opt-in moment, and the disable path is buried in flags or enterprise policy settings.
• –If the visible AI entry point still uses the cloud, the local 4 GB model feels like infrastructure cost shifted to the user without an obvious benefit.
• –This sets a bad precedent for browsers and apps shipping local models first and explaining them later, especially on privacy-sensitive desktops.
