This sort of moving the goal posts is not convincing at all. First it was "batteries will never scale to grid usage" now it's "early days of production of a brand new chemistry are only at 9GWh". You seem to think that is somehow an indictment of the technology rather than a statement of an amazingly quick scale up, with no signs of stopping. That's just bad judgement to say "a rapidly scaling tech is at GWh scale even without much demand therefore it's useless".

Meanwhile, the statement that "fusion has been achieved in a lab" is optimism and wishful thinking beyond words. What energy return did that get? What was the cost? When will there be GE of generation, mic less basic safety engineering?

Those who advocate against the shipping reality of batteries, and moreover assume that they will get more expensive, are not using numerical thinking and are not thinking like scientists, engineers, or technologists. They are merely rooting for a tech like a sports team. Nuclear does not need any more fans, it needs engineers and scientists that can achieve some sort of radical breakthrough that makes it a desirable tech.
