It's Not Me, It's Known

The evolution of developer confidence in three simple steps:

1. Junior dev: "I don't know what's happening" *frantically Googles error*

2. Mid-level dev: "I don't know but I'll figure it out" *opens Stack Overflow with determination*

3. Senior dev: "It's a known issue" *closes ticket without explanation*

The real senior dev superpower isn't knowing everything—it's knowing how to make your ignorance sound like industry wisdom. Bonus points if you say it with enough confidence that the client thinks it's part of the roadmap!
