The answer, of course, is no. The author makes a few valid points but many more invalid points.
Are There Too Many Women in IT?While it is true that programmers aren't very visible to 11-year-olds, that does not mean we shouldn't make them aware of the field. Careers that are interesting to 11-year-olds are not necessarily the same as the careers that are interesting to 22-year-olds. It is
not true that people who haven't programmed before they are 18 aren't interested. They may not have seen the many applications of programming that make Computer Science interesting. I am one of those people who didn't program until I was a freshman in college.
I'm sure you have more thoughts to share, so I'll end there.
