The dad joke of programming has arrived! This pun plays on the double meaning of "C" - both as the programming language and the verb "to see." Python developers wear glasses because "they can't C" - implying they're stuck in a language without pointers, manual memory management, and all those lovely segmentation faults that C programmers get to debug at 3 AM. It's basically saying Python devs are visually impaired to the "real programming" world. Meanwhile, C programmers are squinting through bloodshot eyes after hunting down memory leaks for 12 hours straight, thinking "at least I can C!"
