Should you study Maths and Physics instead of Computer Science?

I completed my degree in Computer Science with Image and Multimedia in 2001. It seems that 2001 was quite a popular time for new computer science graduates.

However, it looks as though people are starting to move away from computer science degrees and I can only speculate that it's in favour of maths or physics instead.

Jobs requiring a good deal of maths knowledge are considered to be some of the best jobs that a human being can do.

So why do a computer science degree when you could get most coding jobs with a maths degree and have all these other options available as well?
