The big benefit in my experience was that I could have a program with real users, that did have errors (from me being new to Elixir and not knowing better) and still not experiencing downtime.
Instead, CPU or Memory would increase over time, hit the VM limit, kill and restart.
So later when I noticed this, I could debug and fix it without simultaneously fighting a prod incident.
