First the article is biased towards Flakers like Flinders (did you expect anything else).
Secondly fact is Tesla and other auto giants like Audi etc..will need lots of Graphite and I mean lots for the Gigafactory.
Thirdly demand for Graphite at $13.5 Billion will not decrease, in fact will increase no matter how much the "old economy" slows..graphite belongs to the 'new economy".
Zenyatta has the best product better than synthetic so go figure.
