An expert is expected to know about his/her field of expertise beyond the 
mere nuts and bolts so that that person can give informed advice. The 
history of a trade is part of that, but knowing history is also a proof of 
intellectual curiosity. Experts who are so narrow-minded that they can't 
reason beyond the immediate issues don't make good experts, or even good 
professionals.
