"I can remember sitting and listening to it beep, gurgle and churn as it processed commands. I remember how the screen lit up in front of my face. There was something intoxicating about the idea of dictating everything the computer did, down to the smallest of functions. The computer gave me, a six year old, a sense of control and command. Nothing else in my world operated that way."
