[...] But in the mean time.... he or she can learn some post processing skills as well.
Which brings us full circle to the original post. Is post processing cheating?
A purist would say that correcting that image after the fact is cheating and the photographer should continue to create failures until they get it right in the camera. Although one can argue that the results from improper use of the camera and the difficult lighting scenario results in a lie created by the camera.
The flip side to that is there is an understanding of the limitations (at time of exposure) of both the camera and the photographer BUT there are methods for correcting those limitations, therefore we can (and should) take advantage of such tools.
In the latter, the question then becomes a modification to the original question to ask, at what point of manipulation does it become too much, thereby rendering a lie?"
I feel that in order to properly answer this question there needs to be some common ground rules about what ultimately constitutes a lie by the photographer and a lie by the technology because, ultimately, the blame falls on one or the other. Until those rules are set, this argument will forever be subjective.
