Can we say that high-level languages ​​encapsulate the code of low-level languages?

Question

Programming languages

Please correct me if I'm wrong somewhere or missed something, but the main question is in the title. For example, CPython is written in C, which means that C code is hidden in it, and those who write in Python do not need to know what is happening there at the C level. In turn, Python itself has functions, such as sorted (), which hides the algorithm sorting. And because of this pyramidal structure, the code of high-level languages ​​is slower. But is it really only a "reference" to a low-level language that causes a slowdown in work?

Answer 1

No. High-level languages ​​simply move away from low-level constructs.
For example, there is low-level machine code , below which there are only electrical signals.
There is assembler , which abstracts from machine code and already works at the instruction and register level.
There is C , which already works with variables, pointers, and structures.
There is C++ , which already has objects, inheritance, and other OOP.
And there is python , which is simply interpreted.
And it has dynamic typing and a garbage collector.
Well, high-level language != slow.
As an example - Rust, which has very high-level abstractions, but at the same time it is not inferior to C either in speed or in memory consumption.
At the same time, a high-level language is not always built on top of a low-level one - very often a compiler / interpreter is written that immediately leads it to machine code. C libraries also produce machine code as a result.
