This is really DANGEROUS. I can almost imagine a mechanical, electrical, aeronautical or materials engineer having become so by not mastering their skills and out of choosing what to study and what not during their university years... -"Dude! You didn't insulate the Columbia Space Shuttle properly!!" -"Look man, back in my university years I chose not to study thermodynamics, nor did I have to master transport phenomena. That's why I am an aeronautical engineer with a major in transgender studies and emotional intelligence"... That'll be the day.
