Null References: The Billion Dollar Mistake
Tony Hoare introduced Null references in ALGOL W back in 1965 "simply because it was so easy to implement", says Mr. Hoare. He talks about that decision considering it "my billion-dollar mistake".
Every so often, I think back to this presentation about the legacy of null.
I first watched this back in college, and it is absolutely fundamental to how I (try to) structure my code to this day, especially when a language has little-if-any null safety built-in.

👀 Incredibly interesting trial. I always enjoy seeing expectations thoroughly smashed, and this is no exception.
