It is the same with any new technology. Not too many years ago digital cameras were the same.

Lithium can apparently be extracted from seawater..but with the expense that won't be done.
That's a matter of political will. Once extracted lithium can be recycled.

Someone was trying to get me to watch a youtube video claiming it would take 10,000 years to extract the lithium needed for cars

The problem I see with electric vehicles is the batteries.
Am I being unreasonable to extrapolate my experience with laptop batteries on to vehicle batteries?
