I can’t speak for everyone but I think of the C++ of today as being dangerously close to the C++ of 1998 because there is so much 1998 C++ code still being linked into most C++ projects. C++17 is incredibly powerful but it’s also hard to wield correctly and most people don’t have those skills yet (and almost none did while writing that 1998-originated library you eventually find yourself need to use). It’s not just the language that matters, it’s how that language gets used and by whom.
