As a non-CS engineer who writes software for a living, I can definitely say that there are times that I wish I had formal training in algorithms, parallel data structures, compilers, operating systems and hardware. There are many times that I need to rewrite my code because of non-adequate design. Other times I reach corner cases that take me too long to debug, only to realize much later that there was a lower-level explanation for the unexpected behavior.
