Python is memory safe? Can't you access/address memory with C bindings?

Why wait and hope for C++ to get where modern languages are now? I know there's value in the shared experience in C++ that if adapted would make it stronger, but I can only see a development of C++ having to force a drop of a lot of outdated stuff to even get started on being more suitable.

But the language is just not comfortable to me. From large amounts of anything creating undefined behavior, the god awful header files which I hate with a passion, tough error messages and such. I also met a fun collision of C++ in Visual Studio and using it with CMake in CLion.

I've just started looking at rust for fun, and outside not understanding all the errors messages with the bounded stuff yet, figuring out what type of string I should use or pass, and the slow climb up the skill curve, it's pretty nice. Installing stuff is as easy as copy pasting the name into the cargo file!

Rust is just the prospective replacement of C++ though, people act like the White house said that C++ should be replaced by rust now. But the just recommend it and other languages, C# will do for a lot of people that does not need the performance and detail that the aforementioned languages target. Python is targeting a whole different use, but often combined with the faster ones.

C++ will live a long time, and if the popularity dies down it will surely be very profitable to be a developer on the critical systems that use it many years from now. I just don't think an evolution of C++ is going to bring what the world needs, particularly because of the large amount of existing memory related security vulnerabilities. If things were good as they are now, this recommendation would not be made to begin with.

I totally agree with this comment, and on top of that I would recommend anyone who really cares about the current state of affairs regarding safety in C++ to read this overview: https://accu.org/journals/overload/32/179/teodorescu/

Quote:

Personally, I am not convinced that in the near future, C++ can do something to stop this trend. C++ will leak talent to other languages (currently Rust, but perhaps in the future to Cppfront, Carbon, Hylo or Swift). If the progress towards safety started in 2015 as Bjarne suggested, the last 8 years have seen very little progress in safety improvements. Even with accelerated efforts, the three-year release cycle and slow adoption of new standards will keep C++ a decade away from addressing major safety concerns.
