Adams has become a controversial figure in recent years. Regardless of what you think of him, as someone who has worked in Corporate America for over a decade, there really isn't anything quite like Dilbert to describe the sort of white collar insanity I've had to learn to take in stride. My first workplace as a junior developer was straight out of Dilbert and Office Space. I have a gigantic collection of digitized Dilbert strips that best describe office situations I've run into in real life – many of them including the pointy haired boss.
He's expressed a lot of what I would consider... stupid opinions these days, but I would be sad to learn he's no longer with us.
Probably also because, like e.g. "Yes (Prime) Minister", part of the depicted did come from anecdotes, instead of fantasy.
