Tech is getting better but common sense is not. You cannot just flip a switch and change the world. Takes time to make it feasible.Maybe this is how people felt when cars were invented and some wanted to keep their horses Unfortunately it is happening. Not sure at what pace, although it seems to be steady and increasing. If the liberals and most democrats had their way, it would have already taken place regardless of price, pollution, etc. The batteries are getting better and cheaper, and will continue to do so. It's like any other technology. Use will just expedite the technologies improvement speed.
