While I don't know whether he's right or wrong, he definitely mentions the industry in the article. He first says, "computer science and engineering are the few fields in which industrial demand makes it sensible to get a Ph.D" and later, "there are hardly any industrial jobs in the physical sciences". Other professors and PhDs I've talked to have basically said the same things as he says here. There are definitely jobs for PhDs in CS in industry, but whether you would be considered a "scientist" for those jobs is debatable, as most of the time you don't have the same level of freedom you would have in academia (or at least that's what I've been told).
