Obama is suggesting 'computer science' as now being a new fundamental skill. I would change that to 'programming'.

Most people do not question whether math is a fundamental skill. Programming is actually very similar to some types of math work in school, but with a heavy focus on practical problem solving skills using technology.

So the question you ask is similar to the question that many people ask about their algebra or calculus classes. But in the case of computer programming, I think it is even easier to see how it can be directly applied in many fields.

Basically the observation is that people need strong technology skills to contribute, since technology is core to nearly every aspect of life now, and programming develops core skills that can help with many types of technologies.
