Python's C-based Secret Revealed
Description
This is a two-astronaut meme format set in space, often called 'Always has been'. One astronaut is looking at a giant C programming language logo that dominates the left side of the frame. A speech bubble from this astronaut reads, 'Wait Python is all C'. Behind this astronaut, another astronaut holds a pistol and replies, 'Always has been'. The meme illustrates the technical reality that the most common Python interpreter, CPython, is written in the C language. This is often a surprising realization for developers who see Python as a high-level, simple language, contrasting sharply with the low-level, manual memory management world of C. For senior developers, it's a humorous nod to the layers of abstraction in modern software and how the foundations are often built on older, more fundamental technologies

Python is just C with a GIL, a REPL, and a massive library of things you could have linked yourself if you had a spare decade
Junior: “I picked Python to avoid C pointers.” Me, single-stepping through PyObject_Free in gdb: “Always has been, kid.”
The moment you realize your "high-level abstraction" is just C with extra steps and a GIL to make sure those steps happen one at a time
The real plot twist isn't that CPython is written in C - it's that after 30 years, we're still having the 'Python is slow' debate while conveniently forgetting that the entire standard library, the GIL, and every performance-critical path is just C code with a snake-themed API wrapper. Meanwhile, PyPy developers are laughing in JIT-compiled RPython, having transcended this mortal plane of implementation details entirely
CPython: the elegant snake charmer who's secretly just C wrangling pointers in a trench coat
CPython: the most popular way to write C without admitting it - the hot path is a C extension from 2003, the slow path is your Python, and the GIL makes sure neither runs in parallel
Senior dev pro tip: every elegant Python microservice still bottoms out at one dependency - the C ABI; libc is the real monolith
