The Lithium scarcity scare reminds me of all the peak oil hysteria (which I'll admit I succumbed to as a teenager.. 2009 being doomsday back around 2004 I think). You can't use existing reserves as an indicator. If there's a higher need for lithium, more companies will look for it, more will be discovered and more mines will open. Probably prices will go down eventually due to economies of scale and new mining techniques (see Teslas battery day presentation for example)
