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.
He has had some questionable views all throughout his life. In his book "The Dilbert Future", which was from 1997, the last 2 chapters are some wacky stuff about manifesting - i.e if you write something down 100 times a day every day it will come true and other stuff like that.
And while that may seem a far cry from the alt-right stuff he eschews, its really not - inability to process information clearly and think in reality in lieu of ideology is the cornerstone of conservative thinking.
The actual cornerstone of conservatism is an instinctual preference for stability, order, and the familiar. The danger arises when this instinct is hijacked by a rigid ideology that resists truth and seeks control rather than continuity.
Which is, you know, what the American right is doing.
