I am extremely skeptical of this . . . Of course, there are plenty of job openings that ask for PhDs, but most of the work does not truly require a PhD. Those jobs are filtering out the vast majority of capable candidates while targeting people who have already shown that they would prefer a different sort of work by doing the PhD in the first place. Is it a surprise that they can't fill the position? Does that mean that CS PhDs can easily get jobs? Perhaps. Does it mean they can easily get interesting jobs? I am more doubtful. Does it mean that producing more PhDs is necessary or even useful? I doubt it.
