Go is fine, but it has its flaws. I prefer Rust because:

• memory safety is a compiler check, not a runtime check, so you catch issues earlier
• locks contain their values, so you can't accidentally do anything unsafe
• no nil (() is semantically different), so no surprises with contracts
• everything is an expression, which lends itself really well to FP concepts
• actual dependency management at 1.0
• pretty much no runtime, so calling from another language is super easy
• targets WASM and microcontrollers
• no pointers (not exactly true)

It takes longer to learn, but I'm about as productive with both now.
