If you default to Arc everywhere, aren’t you essentially just implementing a slow GC?

This type of thing comes up of often when people try the language. They re-implement some part of a program, originally written in a fast GC language, and then wonder why it’s slower.

I feel like the power of the language comes through in specific workloads, or when you take the additional time to avoid naive code. That’s why it is so verbose and rich, it gives you more control. And this is something that advocates often clearly state.
