Some core ideas from the paper for the inpatient (failures, isolation, healing):

- Failures are inevitabe, so systems must be designed to EXPECT and recover from them, NOT AVOID them completely.

- Let it crash philosophy allows components to FAIL and RECOVER quickly using supervision trees.

- Processes should be ISOLATED and communicate via MESSAGE PASSING, which prevents cascading failures.

- Supervision trees monitor other processes and RESTART them when they fail, creating a self-healing architecture.
