Cinematography VS CG

After joining cinematographers.com and searching through some forums I found a post from 2010 discussing the then recent win for Avatar of the Best Cinematography Oscar. Some members seeming quite disgruntled, claiming that computer generated lighting etc should not count as cinematography and the award should be kept to simply credit practical choices. However others argue that the effects team must have had some cinematographical consultation and the decisions to chose that lighting must have been made therefore whether it was a computer code or practical lighting rig it is still cinematography.
This sparks the question, is CG taking over cinematography or is it simply the next step in the practices evolution.
