I sympathise with the author being in the same boat, largely. I just want to emphasise a point... Calculators give 100% correct answers and yet we still hire accountants; for the simple fact that we don't want all to be accountants. People will hire software engineers for the simple fact that they do not want to be software engineers.
If we apply the same argument to software engineering I think it's a good point... just maybe not the one you intended to make.
