The Japanese have been clicking on the wrong technology tree for so many years, and it's really not because of the times. It is entirely because of the Japanese themselves, no matter what new technology they have, they want to rely on this technology to monopolize and then charge for it.

Design service life, which is what many modern enterprises have. As long as it's not too much, in fact, many people can still accept it.

No one is a fool, and no one's money is blown by the wind.
You know the Japanese......
