I would be very careful about applying generalizations here. This article is very vague about what constitutes an "advanced degree in engineering" and exactly what "a decade of experience in the technology sector" means. Not all employees are created equal and this type of study smacks of a certain statistical bias- ie, only the least qualified workers (those lacking the desired skillsets and experience, preferred degrees, etc.) will be the one's out of work. Therefore, to take those who are struggling to find work and project that onto the industry as a whole is to take a fairly protracted view of a complex situation. I'm not saying that the author's proposed explanation is impossible, just that it is only one of many plausible explanations, and without more information it would be a mistake to take any firm conclusions from this.
