Busy pushing daisies, but early on saw it coming.

Siegel & Fox 12/86:

“You know what happened today, Joe?” said one Joe to the other Joe.
“Tell me.”
“I know for a fact that today, the board of governors approved Melamed’s black box.”
“Black box?” questioned the second Joe.
“You know, a machine for electronic trade.”
“Oh my God!” exclaimed Joe. “That could be catastrophic.”
“Yes,” the first Joe agreed, “it is bound to bring on algorithmic trading!”
“Much worse,” said the second Joe, “it will prove that if any loop in a certain kind of three-dimensional space can be shrunk to a point, without ripping or tearing either the loop or the space, then the space is equivalent to a sphere.”
“You mean,” said the first Joe, “that anything without holes has to be a sphere!”
“Exactly,” responded the second Joe, “like a three-way butterfly spread between pork bellies, hogs, and the Mexican Peso.”
There was a momentary silence until the first Joe whispered, “My Lord, it’s the end of our world.”
