training once vs. millions of inferences. And tomorrow inference may naturally include incremental training. Human brain consumes 20% of the body energy. I don't think AI will come to human brain energy efficiency soon, and thus i think AI (and its accessories, ie. like 3d/AR/VR model spaces where and what AI will be operating with) will be a major, if not main, energy consumer going forward. When Google self-driving car passes by the main sound coming from it isn't the engine nor the tires :)
