From today’s XKCD:

A comic contrasts the theory and reality of automating a task, showing how initial coding leads to free time in theory, but in reality, ongoing debugging and development consume all available time, leaving none for the original task.

(Hover text: ‘Automating’ comes from the roots ‘auto-’ meaning ‘self’, and ‘mating’, meaning ‘screwing’.)

As one who has written my share of automating tools… yeah.
