I use Go as a "better C". Though I'm honestly disappointed with even that. My current company, we built an image processing service in Go. It performed poorly and had poor stability (the imagemagick bindings appear to be half-baked). I rewrote it in Java and it is faster, more stable, and the code is much cleaner.

Honestly, the next time I need a "better C", I'll probably pick up Rust or D.

YMMV.

Go is typically structured with many relatively small binaries. Each binary can be relatively self-contained.

The way I've seen Java used, it typically has fewer binaries with each binary bundling many services. Many of which include clients for services at the company but a different org - where that other org can just provide a Guice module that sets up the client to call their service and anything that needs it can easily inject it.

I still hate Java but, damn, I see why it's used at B I G companies.

Also, Go has really poor abstracting capability, which may be good for small code bases where having abstractions is a detriment, but abstractions are the only way to handle complexity. If you have the logic spread out over many different parts (or God save us, copied code!), a new programmer will have much more trouble picking up what the hell is supposed to happen.

In the extreme case, compare reading assembly to a high level language. Sure, each instruction is trivial in the former case, but you have no idea what does the whole do.
