Seems like Shopify wanted a bit of self promotion.  As far as I can tell, the writer agreed with Ms. Wente.  However, the Globe and Mail wouldn't have published a one line response saying, "yes, correct".

The writer concedes that not everyone will code, but that shouldn't treat computers as a black box, and that computer literacy is important.  That's exactly what she said.  The writer's comment about not teaching is also silly, since Ms. Wente has spoke out about silly fads in teaching math too.

The writer basically says he doesn't code daily, but uses the logical thought process to solve complex issues.  How is that skill specific to coding.
