Programming evolution Memes

Back in the day, you'd write a naive recursive Fibonacci and call yourself an idiot. Fix it with fib(n-2) instead of fib(n) and suddenly you're a genius. Simple times. Fast forward to modern Rust development: someone uses matrix exponentiation to calculate Fibonacci in O(log n) time, and AI is like "you're an idiot" because... it's too clever? Then you write proper error handling with Option types, validate inputs, and use the ternary operator because Rust doesn't have implicit returns everywhere—and the response is just "Fine." Not great, not terrible. Just... fine. The evolution here is brutal: we went from celebrating basic algorithmic improvements to being judged by AI overlords who expect production-ready, type-safe, panic-free code with proper edge case handling. The bar has been raised so high that doing things "correctly" doesn't even earn you praise anymore—it's just the baseline expectation. Also, shoutout to whoever is calculating Fibonacci with Mat2::new(1u32, 1, 1, 0).pow(n)[0, 1] . That's some galaxy brain stuff that definitely came from a LeetCode hard problem.
