“Sometimes at night I worry about TAMMY. I worry that she might get tired of it all. Tired of running at sixty-six terahertz, tired of all those processing cycles, every second of every hour of every day. I worry that one of these cycles she might just halt her own subroutine and commit software suicide.

“The red indicator light just came on. I'm looking at the run-time error report. It's like a mathematically precise way of saying, This is not how you do this, man. Meaning life, I suppose. It's computer for Hey, buddy, you are massively bungling this up. I know it. I know it better than anyone. I don't need silicon wafers with a slightly neurotic interface to tell me that.”
