C++ continues to be the dumping ground of paradigms and language features. This proposal just aims to add even more to an overloaded language.
C++ programmers mocked languages for being dynamically typed then they introduced
auto, they mocked JS for callback hell and introduced lambdas, they mocked Rust devs for being lowskill C++ devs who can't manage their own memory and now they are admitting they can't manage it themselves either.It's going to be come like the x86 instruction set or windows that is backwards compatible with stuff from 30years ago just accumulating cruft, unable to let go.

I think you could not be more wrong even if you tried, and you clearly did not even read the proposal you're commenting on.
This proposal aims to basically create an entirely different programming language aimed at being easy to integrate in extsting codebases. The language just so happens to share some syntax with C++, but you definitely can't compile it with a C++ compiler because it introduces a series of backwards incompatible changes.
It's also absurd how you complain about introducing new features. Can you point out any language that is not absolutely dead that is not introducing new features with each release?
I'm sorry, you are clearly confused. The
autokeyword is not "dynamically typed". It is called "auto" because it does automatic type deduction. It is syntactic sugar to avoid having to explicitly specify the type name in places the compiler knows it already. Do you understand what this means?Your comment sounds like trolling, frankly.
auto isn't dynamic typing it's just type inference. It still has a fixed type you just don't have to write it. Like var in C#.
Lambdas are just a way of defining methods in place. It has nothing to do with callbacks.
But you're spot on for memory safety. Managing it yourself is risky and if it can be managed at zero cost it seems stupid not to.
I'm aware, but one of the big arguments I've heard about dynamic typing is "I don't know which type it has when I read the code". Well, auto looks just like var in that regard.
Callback definition from wikipedia:
This is exactly what lambdas are often used for in C++.

It really isn't. Neither in C# nor in Java. They are just syntactic sugar to avoid redundant type specifications. I mean things like
Foo foo = new Foo();. Who gets confused with that?Why do you think IDEs are able to tell which type a variable is?
Even C# takes a step further and allows developer to omit the constructor with their target-typed new expressions. No one is whining about dynamic types just because the language let's you instantiate an object with
Foo foo = new();.
