Engineer? Does not require a B.S.? That's bs.
An actual engineer (someone who qualifies to take the Professional Engineer examination) has minimum prerequisites. Among these are a Bachelors Degree in Engineering from an accredited engineering school, 7 years experience in the field, successful passing of the engineer in training exams, and final passing of the Professional Engineer Exam. Then an engineer may use the title P.E. after their name.
Many engineers choose not to pursue the P.E. pathway. These people still hold a minimum B.S. degree in engineering from an accredited engineering school.
It shocks me how poorly informed people with journalism degrees are on this subject.
The people you are referring to as engineers in this article are actually technicians. Often all they require is a two year training program or a certificate program. Some technicians obtain their knowledge on the job. They are few and far between and getting rarer. Thomas Edison was one of them. Nikola Tesla was another, being a technical school dropout.
