That actually seems unrealistic to me. Of course, people will always become better at doing the things they do, and we can always try harder, but many of these issues take time to consider and find during code reviews, and a few just slip by. That's why tools like Coverity exist, but you have to spend time and money to set those up, meaning it's only done when absolutely necessary (or one dedicated person is really pushing for it). Choosing a different language is basically free in the beginning, and it will impact which sort of bugs will be caught by default and which won't. C++ is also massively hurt in this regard by not having a package manager. JS is a very risky language by default, but a few tools just with their default settings will already help massively. I guess Nix could be considered the missing package manager for C and C++, but it's still niche and definitely not a "default" like pip, npm or cargo.
