Speaking seriously, I agree there's definitely a lot of bloat in the new C++ standards. E.g. I'm not a fan of the C++26 linalg stuff. But most performance-focused trading firms still use the latest standard with the latest compiler. Just a small example of new C++ features that are used every day in those firms:
Smart pointers (C++11), Constexpr and consteval (all improvements since C++11), Concepts (C++20), Spans (C++20), Optional (C++17), String views (C++17)
I don't agree at all. For most, linear algebra is the primary reason they pick up C++. Up until now, the best option C++ newbies had was to go through arcane processes to onboard a high performance BLAS implementation which then requires even more arcane steps such as tuning.
With C++26, anyone can simply jump into implementing algorithms.
If anything, BLAS support was conspicuously missing from C++ (and also C).
This blend of comments is more perplexing given that a frequent criticism of C++ is its spartan standard lib, and how the selling point of some commercial software projects such as Matlab is that, unlike C++, linear algebra work is trivial.
