“Let it crash” doesn’t mean keep bashing your head against the wall. Elixir makes it easy to write state machines which reason about different types of failures, but it’s more declarative (this process requires X and Y preconditions, otherwise do Z) rather than imperative (I have to try/catch failures due to X and Y, now do Z). With Elixir you can actually specify that the process doesn’t start until the DB connection is ready, if that was the cause of the failure, it won’t start again (something else can take care of the DB). When the LLM API returns an error you can put the agent in a paused “errored” state and then you can have a different process decide what to do with the error, and pass it back to the main agent when it’s done. This is all really elegant functional code in Elixir compared to try/catches and if statements.
