This x1000 If you want to make a little cross platform binary for some utility sure maybe Go is the right choice, but most of the time people are building a "Web Application" in which case there are dozens of better languages to use
I found Go a better fit than Java & Python for my web APIs/micro-services. I'm not sure what web application are but Go compiles to WASM so it would make it an even more complete solution once WASM gets DOM access.
