If only battery technology had kept up with computing technology.

We'd definitely all be driving electric cars today if that happened.

The best (commercial) batteries today are only a few times better than the ones used in electric cars 100 years ago.

I've read the rate of improvement for batteries is around 8% a year. That's still exponential, just not as good as transistor count. But nothing else improves that fast.
