How are JVM startup times nowadays? Frankly the need to ship with a JVM (modulo graal admittedly) is a drawback, eg for CLI tools - which the author listed as a requirement. Go's static executable story, combined with it's competitive performance - without C++ or rust contortions - is a strong combo when your focus is on startup time and deployment simplicity. (If, otoh, I cared a lot about GC I'd definitely prefer Java - eg for non-fast algo trading.)

Java is a fine language, tech stack, and ecosystem, but I agree with the author and parent commenter that this is a sweet spot for Go. Their decision to use it makes a lot of sense.
