> commercial airline pilots can be described as a 'Boeing 747 pilot' or an 'Airbus A318' pilot. I don't think that's a good analogy. Pilots are operators, not creators. What they do is pretty much defined by what devices they use to do it. Engineers, in contrast, use tools to create new things, and are defined by what kinds of things they create (e.g. civil infrastructure, electrical systems, computer architecture), not what tools they use to create them.
