This week, meet a reader we’ll Regomize as “Wilson” who once worked as the boss of a welding shop attached to an engineering consultancy.

Wilson set the scene by telling us this story came from the early 1980s, when AutoCAD was replacing drawing boards.

“We had a new structural engineer who those of us in the shop quickly identified as an idiot with a degree,” Wilson wrote.

One day, said idiot decided that the computers used to run AutoCAD needed to be cleaned and that the welding shop was the place to do the job.
