Most developers have only a fuzzy sense of what happens between their fingertips and the silicon. This episode traces a single Python `print("Hello")` statement through every layer of abstraction: CPython bytecode compilation, the virtual machine loop, glibc buffering, the system call boundary, the Linux kernel's VFS and terminal driver, and finally the hardware itself. We contrast this with C and Rust's approaches, examine why Python generates 562 system calls vs C's 34, and explore what "high-level" and "low-level" actually mean concretely — not as textbook definitions, but as countable…
