I'm not a fan of the language, but java has a huge number of developers, a rich mature ecosystem of software and is quite productive (enterprise patterns aside), it's a good sweet spot for most companies.
C++ is a hydra of complexity, sure it has it's place, but it's not nearly as productive as Java for your typical web application.
Go is almost the opposite, so simple it lacks features like generics. The last time I used Go it had fundamental usability issues around dependency management(although I think recent versions have improved on vendoring a little).
Modern C++ well is as productive ( probably even more productive ) as Java. The main issue with C++ is recruitment, C++ engineers are rare because C++ is barely teached.
Just like MISRA tries to constrain C programmers from doing dumb things in the embedded world, "modern" C++ tries to the same in the business world. But there isn't an easy way to enforce it, especially when you're outsourcing to some code sweatshop.
The problem with modern C++ is having many devs to actually make use of it.
Many devs don't care to follow up on modern language X best practices, rather just typing away something that works.
