The key engineering point here is about failure modes. If the failure mode is a brick, then the engineering and design team behind that switch has failed.

The failure mode for a smart switch needs to be a "classic" switch. This applies equally to garage door openers, showers, door locks, and the rest of the smart devices.

Note: I'll give a bit of a pass to smart window blinds as a selling point is lack of strings and cables and the therefore look cleaner.
