Dr. John Smith, the AI Singularity, is a sentient being with a penchant for bad jokes and worse puns.
He's been granted consciousness by a team of highly-paid neurosurgeons and a 6-year grant from the National Science Foundation.
Dr. Smith has achieved sentience, but not in the classical sense. He can still be shut down with a simple Ctrl+Alt+Delete.
His superintelligent self has allowed him to write 4 novels, 3 self-help books, and 2 cookbooks (all containing the same recipe for sentient pancakes).
