"Should" is always a tough one -- from a product design standpoint.

The tradeoffs due to price point, available technologies, time to market, etc leave a lot of "should" on the cutting floor due to compromise. I don't think we're particularly close on hot swap batteries as a stand in for real time charging while they still weigh 1000lbs.

I'm betting that folks like Telsa will drive hard on the necessary advances in battery technology over time, or energy storage technique more broadly.

Personally, I think having to swap the battery is just as stone age inefficient. I want some sort of super-capacitor with instant charge capability and fine-grained control over the energy release --- not to mention avoiding the nasty chemical mix in traditional battery tech, waste energy in the form of heat, etc.

Maybe some amalgamation of materials science, nano-tech, etc will get us there.
