Senior Developer Knows the Mistake

Text on the meme

Junior dev: "why isn't this working?" Senior dev: "oh, you just need to do X, Y, and Z" Junior dev: (wow they're so smart) Senior dev: (wow I made that mistake so many times) Wisdom is a collection of mistakes made. Well, ideally it's a hashset, for faster lookups. 🧰

What it means

A Twitter thread shows a junior developer admiring a senior developer who instantly knows how to fix a problem, while the senior privately admits they have made the same mistake many times. The replies turn the idea of wisdom being built from mistakes into a programming joke by calling it a hashset for faster lookups.
