Ah yes, the classic programming language roast disguised as a dad joke. The punchline here is a beautiful double entendre: Python programmers allegedly wear glasses because they "can't C" – as in, they can't see without corrective lenses, but also because they literally can't code in C, the notoriously difficult low-level language that requires manual memory management and makes you question your life choices. Python devs are used to their cozy high-level abstractions, automatic garbage collection, and readable syntax that looks like pseudocode. Meanwhile, C programmers are out there wrestling with pointers, segmentation faults, and malloc/free like it's 1972. The joke implies Python folks need visual aids because they've been sheltered from the harsh realities of systems programming. It's the programming equivalent of saying someone who only drives automatic can't handle a manual transmission.
