I work for a fortune 500 Japanese tech company developing software.
Its a cultural problem Japanese cant create software. There is no sense of "Hacking".
For them everything has to be formalized with detailed processors, costing and KPIs. There is a huge bureaucracy to slow down development as much as possible and complain when things get delayed.
They look at the company as a factory that output lines of code, bugs as product defects and treat developers as factory line workers who are insignificant and easily replaceable.
My sense is the hype just died down. There are genuine cases where message queues are the correct solution. But since most of the developers are clueless they just jump on the latest trend and write blog posts and make Youtube videos.
This effect has also happened with microservices/monaliths, lambda/serverless, agile/scrum(still no concrete definition on these). Even cloud as a whole, there are so many articles of how companies managed to cut cloud cost to a fraction just by going bare metal.
Most wealthy people or companies today aren't really wealthy. They just have stocks with imaginary value. Most of which were bought by someone else's money and need to be repaid at some point.
