That's a really wild, miserable reading of the strip. For one, Adams himself was a manager, not an engineer, so he had more in common with the PHB, or even dogbert/catbert than Dilbert. For another, he explicitly said Dilbert was based on a specific, undisclosed person he knew. For yet another, many strips were based on anecdotes/stories sent to Adams by his readers.
Scott Adams put himself on a pedestal above anyone else in his comics; he was Dilbert. The only smart person in the room. He was always a celebrity obsessed with his own existence. Little difference between him and Tim the Toolman or a Kardashian.
Low effort contributor whose work people laughed at due to social desirability bias. No big loss.
