I equate garbage collection with larger static binaries. Julia's static binaries are especially large since they package the entire sysimage. I'm excited about StaticCompiler.jl because, by cutting out the sysimage, it promises to make Julia more competitive with other garbage-collected languages like Nim, Go, Crystal, etc., all of which produce relatively small static binaries.

However, like these other garbage-collected languages, Julia is unlikely to ever compete with the likes of Zig, Rust, C++, etc. which produce even smaller static binaries since they don't have to ship a GC runtime. That's why I specified garbage-collected languages as, in my opinion, the addition of proper static compilation will allow Julia to completely supersede other garbage-collected general programming languages but not manually managed systems programming languages.
