I'm uncertain if MY code works correctly lol. I know many code-illiterate folk; some of them I call "boss" or "client." They get along fine dining on my spaghetti. I do likewise never touching the wheel/pedals on my car's 45-minute commute to work.

Will someone eventually be scraping me off of the highway? Will my bosses stop printing money with my code? Possibly! But that's life -- our world is built upon trust, not correctness.
