If we accept that battery technology is rapidly improving and will be an order of magnitude better in the future, then those points of cletus' argument are indeed invalidated - the root comment is arguing that electric cars will not be the future because (e.g.) batteries are too heavy and take too long to charge. For internal consistency, the argument should have read "batteries will continue to be too heavy and take too long to charge".
