Alec Rawls at Error Theory has a provocative posting on a "mirror hanging in the sky"* at Earth Day 2030: "A new eye blinked open upon the world".
*Comes from a vaguely remembered Donovan song, "To Try for the Sun"
"Mirror, mirror, hanging in the sky,
Won't you look down what's happening here below?
I stand here singing to the flowers,
So very few people really know."
