I.. uh. I hate to break it to you, but that's not as deep of a moat as this reads like you would believe it is.

Engineers (like me, fwiw) would love to believe all these things about themselves, but they're not really true.

Of course, there is a difference, but the difference just doesn't matter all that much in the real world. Markets do not care.

Which isn't to say that people shouldn't know their worth. But it is to say that one can better defend their worth when armed with an accurate assessment of reality.
