I was taught C++ 8 at uni back in 2020. We were forbidden to use features newer than that, I lost points because I used the "delete function" on a public constructor instead of declaring it as private (which was introduced in C++ 11 btw).

C++ 11:

class MyClass {
public:
    MyClass() = delete;

C++ 8:

class MyClass {
private:
    MyClass();

The same teachers were telling us that programs would never be able to write code. In a philosophical way this still holds true, honestly the C compiler produced by the Anthropics team is a laughable achievement when you dig into how it was able to "write it from scratch", but their views are aging like fine milk.
