Mechanical sympathy in Go? When you think you've seen it all... Go is not a high performance language which made a lot of decisions that don't lend its usage to be nice in scenarios where people want C and Rust. However, with the hype around it, the management continues to make decision, to everyone's detriment, to utilize Go in performance sensitive infrastructure code which one could write in Rust or C# and achieve much higher performance. |

Go is all about mechanical sympathy, and is absolutely a high performance language. I guess it all depends on your context, though. If you're used to writing assembly or C, things may look different.
(A "for" loop expresses much more mechanical sympathy than a list comprehension, as an example.)
But at least in the context of application services -- programs that run on servers and respond to requests, typically over HTTP -- Go is the language to beat. I've yet to see an example of a program where the Rust implementation is meaningfully more performant than the Go implementation, and I've got plenty of examples where the Go implementation is much better.
