ファン of the アバター

uhm I know I shouldn't answer with another 質問 so, I'm pretty sure there is not another season of avatar. And if there actually is one: WHEN WHAT HOW? To the other questions, I might say that after talking with my chemistry teacher who turned out to be pretty cool and is also ファン of avatar, I asked him if there was a possibility in which we get through the evolution of not just controling and bending metal but at some point we would be able to do it with our minds. He supported my theory, of course it is something we might never be able to appreciate...
