The samurai died out though, where as Japan’s unchanging ancient businesses managed to remain. I wonder if quick thinking isn’t just what leads one to an early end, business, life, or otherwise.
Of course any endeavour can meet an early end due to carelessness or because of not stopping and considering whether what you're doing is actually a good idea. But carelessness would probably not have been held in high regard by the samurai, and I generally fail to see a simple connection between to the samurai class becoming outdated and a preference for "quick" thinking.
Edit: In other words, many people are dissatisfied with the contemporary world set up by merchants and bureaucrats. I don’t see it as misguided or quaint for them to look to the samurai ethic as a more appealing alternative. Its historical accuracy isn’t really relevant, as all history is story creation.
Eastern cultures didn't really have religions universally promising to provide all the answers/solutions like western culture had, so they developed very interesting alternative ways of addressing these struggles in life.
Almost as if the two are unrelated concepts.
