On my private feed, ART said, Take care of them. And yourself. Before I could come up with a reply, my awareness of ART, its cameras, its feed and comm, the humans working and talking to each other on ART, or using the comm to talk to Mensah and the other humans on the Preservation responder, dropped away. I had expected it to be immediate, but the voices and signals gradually lost volume, fading into an echo, then into nothing.
