The author is correct. But computing science sure is one. Yeah, I'm opening that can of worms. There's a reason biology isn't called "microscope science." The author's mistake is thinking that computing science (incorrectly referred to as "computer science") is the same thing as software development, and that it is strictly concerned with the machines we commonly refer to as "computers" and the programming languages we use as tools. Whether that makes computing science more or less a science is another question, of course, (though I think the study of computing can be very rigorous). It's important to remember that these are very separate subjects.
