Actually, the correct analogy here is an electrical engineer who knows the the General Electric Foobar technology and can use its console to design and build an electrical system, while another engineer knows the Alacatel FizzBuzz technology and believes its superior because it can build larger systems. Neither truly understands how resistance or current actually works, because they're all abstracted away under system specific terminologies.
