It wasn’t malicious. The devices weren’t breaking; they were conversing. The patch had done something improbable—it had given them a shared voice, a little communal awareness that sidestepped the usual stream of notifications and diagnostics and, instead, reached for language.

He chalked it up to his imagination and settled down to dinner.

An engineer from the vendor came down from the city a week later. He tested ports, reset protocols, and peered into headers and checksums. “It’s a patch,” he said, more to himself than to anyone else, “but it looks like an emergent behavior.” He was meticulous and serious, but even he—educated in the cold logic of firmware—paused when a line of smart bulbs spelled out THANK YOU in tiny, incandescent letters.
