Comment: The guy's stereotypes about girls / women are insulting & demeaning.

Things to consider: teenagers & young adults don't know much about careers & job choices.

But they have probably watched tv shows about doctors & lawyers so doctor & lawyer are popular career choices. They have used the services of a dentist, doctor, veterinarian, pharmacist, nurse, teacher.

They don't know much investment bankers, scientists, engineers, computer programmers, university professors, etc.

Health care jobs have better job security.

Engineers and computer professionals have been laid off in recent years.

So the smart female students end up in health care, business, law, teaching, science research.

They might consider engineering to be a predominantly man's job.

But surely, sitting in front of a computer all day could be considered a gender neutral job. Let's guess that computer science was not a popular program choice in previous years but it might be more popular now (more media exposure now).
