C++14, 17, and 20 do seem to add, as Bjarne says, "significant ... complexity" to what has always been a daunting language. 150 experts--C++ experts, to be sure, but also domain experts--all bringing new features that address their personal itch for the language.
Just compare Java 10, C# 7.3, Python 3.6, .... to their initial designs.
However I do agree with you and Bjarne, having also submitted this link awhile ago.
C++20 should have been fixing what was left from C++17, specially regarding concepts and modules.
Instead there are a plethora of other issues, and some of them it isn't even clear what is coming with C++23.
I‘m not terribly keen on museums, but I visit it every single time.
The sheer amount of art on the ship is breathtaking.
And the story of the ship is more fascinating than the short excerpt here shows.
For some reason I never made the correlation between overengineering and the Vasa. I probably classified it subconsciously as a front-end issue.
Bjarne has spoken, and his warning should be heeded.
