Doing it on a whiteboard is an academic computer science problem.

Doing it on a computer is more along the lines of a software engineering problem, though still it is largely academic and counter to one of the tenets of good software engineering (that all code is a liability, and thus new/non battle tested code should be avoided whenever possible).

I wouldn't solve all car engine problems by completely replacing the engine, but if I was hiring a mechanic I'd want to verify he could replace the engine if needed.

If you were hiring a mechanic, why would you test them on their ability to design engines?
