When someone asks if you know any programming paradigm beyond OOP, and your brain immediately goes to "FU"... which conveniently stands for "Functional Programming." The perfect accidental programmer comeback! After 15 years of watching junior devs make everything an object, I've learned that sometimes the best answer to "how should we architect this?" is indeed just "FU." Pure functions, no side effects, and immutability - it's like telling your stateful code to take a hike.
