I appreciate the content of the article but I can't help picking up a dose of disrespect from the author towards exactly the collection of people he is trying to persuade.
I suspect the author is trying to persuade those who make 'very anxious responses from people in tech at anything which suggests that their “core skills” may be devalued' and the reason I feel the tone is disrespectful is because he shows very little empathy for them. On the other hand, perhaps instead the point of the article is to reassure those with the soft skills that they will soon be more valuable than they currently are.
