> engineers are investigated for culpability

Funny how you believe that. Remember the Miami bridge collapse ?

Workers on the ground misplaced one of the supports, and then didn't stop work when loud noises started coming out of the concrete. This was not documented wrong on the design, it was those same companies first mismeasuring the location of the supports, then simply moving them around when they didn't fit.

Who's culpable ? The designers, of course.

Or take Dieselgate. European, German and French car manufacturers systematically and purposefully installed software in the cars to commit fraud on the testers (the government testers knew that this was happening).

Who's culpable ? A single engineer, of course.

Not the regulators that knew what was happening.

Not the European investment bank, who had seen reports on this.

Not Volkswagen management, that had built several facilities explicitly for committing this fraud.

Let's stop pretending the problem with engineering will be solved by assigning blame to engineers. It won't. It can't.

Large scale fraud, committed by management and government is the problem. It cannot be fixed with engineering.
