Tinder, a dating app, has recently updated its Terms of Service. Among minor bureaucratic modifications, one major change aims to battle impersonations. From now on, Tinder will ban web developers who claim to be 'engineers'. While backend- and other types of software developers seem to be unaffected, many believe the ToS will be amended soon to include those as well.
Anyone can build a bridge. Only an engineer can build a bridge that barely stands.
In the same way, the fact that one built a large online platform, that doesn’t necessarily mean it was built with minimal ressources and without taking past or future risk.
Engineering is, as a profession, specifically the application of scientific principles to solve problems the right way, the first time, that is to say efficiently, and with minimal risk.
The fact that one codes, or wields a wrench, or operates a C&C machine does not mean one is applying science to solve problems efficiently and managing risk. These are entirely different skills and professions.
