It is, except for the fact that the future isn't guaranteed, so there could be unforeseen problems with scaling up, and that 50% improvement never gets delivered. As mentioned upthread though, CATL has expertise in that area, and "end of this year" is so a trackable claim, unlike the claims about gallium-based batteries.

I agree. Its also not uncommon that the "old" tech improves incrementally during the same timeframe, mitigating the seeming impact.
