I've been coding professionally in Go and have recently switched largely to Rust. I feel Go is designed for junior developers: it's easy to get started, like with Python, but comes at the cost of verbosity and lack of expressiveness. E.g., you'll have to live with "if err != nil" all over the place. It's good for orgs though because code written by different people looks the same and readable. Most importantly, it's garbage collected, which can be good or bad depending on where you're using it (good because you can be super cavalier with memory, but bad because of stop-the-world pauses).

Rust IMO is much more advanced and expressive. It's a joy to write, makes you think and feel like a developer rather than an assembler that you can feel with Go. IMO it handles most of the common problems with languages well and has probably the best support for Web Assembly if that's your goal. It's not garbage collected, which is critical for systems programming. It is more complex than Go though and takes longer to master. Also, while it's growing rapidly, Rust also has fewer job openings compared to Go, if you're doing this for getting a job.
