Sure, you can shut down and restart your entire application. You could do that back in 1990 without containers, too.

The thing is that Erlang does hot reload at a per-function (or -according to Hebert- sometimes more-fine-grained) level, so nuking the entire program and paying the cost to start it up again is not at all the same thing as -say- using a not-absurdly-priced AWS Lambda [0] or similar to get per-function hot reloading.

By the way, have you read "A Pipeline Made of Airbags"? If not, you should give it a read: <https://ferd.ca/a-pipeline-made-of-airbags.html>. It might be old news to you, maybe, but maybe not.

[0] Good luck finding one, though.

I didn't read that one before, but I share the sentiment. We can't have cool things and it was all dumbed down, so the worst case become a default mode of operation. This didn't happen specifically with hot reload in erlang, it happens all the time at all levels.
