Completely agree that it's off-putting. The author indeed has only ever worked in academia per his LinkedIn.

But disagree that this is a path to unemployment. At work we go very fast and yet I think fast is compatible with each of those points, just not in all situations.

Marc Brooker, distinguished eng at AWS, gives much more useful advice for industry, as you'd expect given his almost 30 years in industry.

From that guys LinkedIn he was in academia and then at AWS. I guess it's better than the professor but hardly someone who knows the ins and outs of the industry. For that you need someone who has had a multitude of jobs at various different types of organizations.
