Maybe I didn’t make myself clear. “Let it crash” is not something that should be thought of at the component level, it should be thought of at the system level. The fact that the application crashes “gracefully” or not is not what is really important. You should design the system in a crash-friendly way, and not to write the application and think: “oh, I believe it is OK to let it crash here”.

Then I don't think you understand how the phrase is used in Elixir/Erlang. The phrase is about letting processes crash.

No need for the snarky comment. If I am wrong, that is fine.

Of course Joe Armstrong could explain what I meant, but in a much better way: https://erlang.org/pipermail/erlang-questions/2003-March/007... (edit: see the "Why was error handling designed like this?" part for reference)

My personal interpretation is that systems must be able to handle crashing processes gracefully. There is no benefit in letting processes crash just for the sake of it.
