I am not yet personally convinced that we will see an EV revolution. Batteries still do, and likely always will, disappoint. I am learning similar lessons on the nickel-iron battery front. We may have to face the fact that gasoline has been the ultimate transportation fuel, and the economists’ picture of universal substitutability may not apply. If EVs can never really outperform gasoline in cost, ease/simplicity, convenience, and robustness—and if they remain expensive to own and maintain, from where will the prosperity derive for us to all have such marvelous toys?
