I can't believe no one's mentioned:

  Computer science is no more about computers than astronomy is about telescopes.
  -- Edsger Dijkstra

Contrary to the beliefs or desires of some, colleges and universities are not vocational training institutions. In the actuarial world, there is a rigorous credentialing process involving a series of exams usually taking a minimum of 4.5 years to complete. However, even with all of the exams passed, without experience you'd be put into an entry-level position. If your experience is in one field of insurance and you want to get into another, that experience won't count for much in the new field and you'll probably be starting near entry-level again.

That's for good reason. Academia is for teaching you known facts and theories, and how to think for yourself. Experience in an industry teaches you how to do a particular type of work so that other people are willing to give you money in exchange for your labor. These are inherently different activities, though the former can weed out some inappropriate candidates for the latter.
