 there's a big shakeout usually the the companies with the best cost advantage generally survive that and some of the weaker ones go under i think what we're seeing right now is that this price dynamic is going to make it very hard for some new entrants to enter the market and there are a lot of new entrants who are trying to enter this market over the next little while so we're watching that dynamic closely but i'm anticipating there's probably going to be a bit of a shakeout in the next few years what about technology as batteries get better we need less of them is that also a factor here
