I'm trying to recall a short story from the 80's that, as I think back, seems prescient of several computing technologies we're currently using.
There was an AI capable of self-improvement and a human friend, possibly the engineer. The talking computer personality may have been based on FPGA. He was definitely built using something called a "Josephson Junction" because one of the emotional parts had him pleading
"Hurry, my JJ's are melting"
as parts of his mind were beginning to permanently fail.
