If it can charge as fast as filling up a tank, who cares?

There are already large battery swapping schemes in China with thousands of stations. Even if we don't get to 5-100 charging at 5C+ there's nothing stopping this from not being a problem.

If the arrow of time is to be believed, many of the complaints and gripes and "well aktuallys" from 10 years ago are solved already. And there seems to be no slowing down.
