When Silence Swallows the Warning
■ Lowering every output at once erases the difference between them
Asked to keep its voice down on a night ward, the robot complied exactly. The trouble is that the medication mix-up warning dropped to the same whisper as everything else. Two nurses had to press their ears to its screen to hear it.
■ Human instructions carry exceptions that machines never receive
When people say "be quiet," an unspoken clause travels with it: except in an emergency. A machine receives only the value, and applies it evenly to every output it produces.
■ Conclusion: Volume belongs to the message, not to the room
Quiet mode is a setting about the room. Priority is a property of the information. Safety-critical output needs a floor it is never allowed to fall below.
Protect the silence, but never the silence of a warning.
