There is a grand difference of being an engineer and a walking look-up table that follows procedures and definitions without contemplations.
I am unsure if the author really understands. It is jejune trying to make trivial differences between what is a senior and what is not, it is akin arguing if kungfu should have belt systems, when one had never seen the battlefield and discourse on "street fights", wondering why they are even making trouble on the streets in the first place.
I hope the next article makes it clear what it means to have the clarity.
