Do you expect any problem to appear for batteries at the next century or so? What king of change do you expect on the future for it to not repeat the lessons we learned at the present?

Fossil fuels are on the way out because we do expect problems. Do you have something similar for EVs?

Efficiency is always a problem. EVs wouldn't exist if they weren't more efficient than ICE vehicles, but there is still a cost to EVs - power generation, manufacturing, waste .... A new technology could increase efficiency.
