Calm down mate, don't be so worked up over a random article posted in HN.
The OP is talking about taking pre-emptive maths course and accelerated learning not particularly taking a full course degree in math.
Personally, I think engineering students will benefitted more if learning engineering maths in their pre-universities courses namely matriculation, A-Level or Baccalaureate, rather than spending few years learning the subjects during their main engineering degree. It helps the student focus and minimize the pre-requisites.
