Still Prius? Or for more 20 years?

2016/8/19 Still Prius? Or for more 20 years?

TOYOTA started to sell Hybrid car Prius 18 years ago.
What is next generation car?
Still hybrid car? Or for more 20 years?

From Gasoline to Hybrid, next, from hybrid to electric? When it comes?

I remembered that Carlos Ghosn, the CEO of Nissan, said "Hybrid car is filler to the elecric car". It seems that there is problem for it.  Maybe not only technical problems, but other's problem.

None feedback

2016/12/29. None feedback from others in Japanese company Feedback is not always visible or sound , especially the fact of feedback is hidden by various suits. And in Japanese company, I often see the scene that ignorance to the people who did careless mistakes. Others don't say anything about the careless mistakes in front of the person, but in background, others speak ill of the person. This is none feedback. None feedback from others is very bad feedback, but in Japanese company, it is often. Why none feedback happens? In my experience, there are some reasons. When the person who made mistakes is upper than others, others want the person to fall out. When the person is equal level to others, others want the person not to promote. When the person is lower level, others want to make the person the targets for inner circle. I rethink that none feedback in company is bad signal for organization... None feedback happens when the company is bad statements!!!
