Who says people are optimistic? Most are criticizing, and I'm one of the few who are optimistic.

New energy vehicles were initially abandoned technology because the batteries were too big and expensive. With technological advancements, there's a chance to revive what was once considered abandoned.

Tesla abandoned battery swapping model because many American families live in houses and can charge in their own garages. But China's situation is different—less than 20% of households can charge at home, and public charging stations are not as developed. Fast energy replenishment is a pain point, which can be solved by range extenders, battery swapping, or supercharging, each with its pros and cons.

Range extenders sell well in China, but Tesla doesn't use this technology.

I think battery swapping not only provides fast energy replenishment but also solves battery warranty issues. In a few years, the first batches of new energy vehicle batteries will reach the end of their lifespan, and the advantages of battery swapping will become obvious. I hope Nio can survive until then.
