The assumption there is that lithium is fully optimized. It's not.

Granted, but lithium has also had a significant amount of additional R&D, particularly in manufacturing.

Time will tell if sodium batteries can be competitive, I don't know that it's clear yet.

Lithium and sodium are similar enough that it's hard to imagine that some of the learnings from lithium haven't translated to sodium.
