I think it is a little bit overestimated to think that programming in C will make you understand what is really happening. No one is saying that but I just want to make a general note. A programmer might be succesful in using pointers, memory allocation/ deallocation, pass-by-value vs. pass-by-reference etc. but still had a very imaginative mental picture about the things under the hood. If you really know things it may be a surprise to see that some people feel it very differently. People are very imaginative and they will fill the knowledge gaps with something they are comfortable with. And they may get very far.
