What does 'let it crash' mean?

Summary

Instead of handling every unexpected error defensively, let the process crash and rely on a supervisor to restart it in a known-good state. Expected errors are still handled with tagged tuples.

Longer Answer

This keeps code simple and isolates failures, because processes share no memory.

Key Points

• Supervisors restart failures.
• Isolation limits blast radius.
• Handle expected errors explicitly.
