Being an engineer is neither having a degree in engineering which he doesn't have nor managing them and it certainly isn't owning a company that employs them. It's working as an engineer.

He continually says dumb things that aren't true or reasonable and has never worked in the field he's a rich boy who bought things with daddy's aparteid money.

He has a physics degree instead of an engineering degree.

I suppose most people don't know that physics degrees are largely accepted as engineering degrees.
