alt Hacker NewsI personally loved using Go 8 years ago. When I built a proof of concept for a new project in both Go and Rust, it became clear that Rust would provide the semantics I’m looking for out of the box. Less fighting with the garbage collector or rolling out my own memory management solution.
If I’m doing that with a lot of ugly code - I might as well use idiomatic Zig with arenas. This is exactly the point the author tried to make.
Your last paragraph captures the tension perfectly. Go just isn’t the tool we thought for some jobs, and maybe that’s okay. If you’re going to count nanoseconds or measure total allocations, it’s better to stick to a non-GC language. Or a third option can be to write your hot loops in one such language; and continue using Go for everything else. Problem solved.

Or use Go and write ugly code for those hot loops instead of introducing another language and build system. Then you can still enjoy nicety of GC in other parts of your code.

Go made it explicitly clear when it was released that it was designed to be a language that felt dynamically-typed, but with performance closer to statically-typed languages, for only the particular niche of developing network servers.
Which job that needs to be a network server, where a dynamically-typed language is a appropriate, does Go fall short on?
One thing that has changed in the meantime is that many actually dynamically-typed languages have also figured out how to perform more like a statically-typed language. That might prompt you to just use one of those dynamically-typed languages instead, but I'm not sure that gives any reason to see Go as being less than it was before. It still fulfills the expectation of having performance more like a statically-typed language.
