Nothing screams "senior engineer" quite like being unable to implement a basic permutation algorithm while simultaneously architecting distributed systems. You're out here designing microservices that handle millions of requests, but ask you to write a function that generates all possible orderings of an array and suddenly you're crying into your keyboard reaching for ChatGPT.
The modern developer's paradox: we can build entire applications but freeze when faced with CS101 algorithms. To be fair, when was the last time you actually needed to manually code permutations in production? There's literally a library for that. But then comes the coding interview or that one random ticket, and you're frantically Googling "permutation algorithm" like you've never seen recursion before.
The real kicker? AI can now spit out a perfect permutation function in 2 seconds while you're still trying to remember if it's O(n!) or O(2^n). Technology truly is humbling.
