In my opinion , I like golang's way better because then you have to be thoughtful about your dependencies and it also prevents any drama (like rust foundation cargo drama) (ahem) (if you are having a language that is so polarizing , it would be hard to find a job in that )

I truly like rust as a performance language but I would rather like real tangible results (admittedly slow is okay) than imagination within the rust / performance land.

I don't want to learn rust to feel like I am doing something "good" / "learning" where I can learn golang at a way way faster rate and do the stuff that I like for which I am learning programming.

Also just because you haven't learned rust doesn't make you inferior to anybody.

You should learn because you want to think differently , try different things. Not for performance.

Performance is fickle minded.

Like I was seeing a native benchmark of rust and zig (rust won) and then I was seeing benchmark of deno and bun (bun won) (bun is written in zig and deno in bun)

The reason I suppose is that deno doesn't use actix and non actix servers are rather slower than even zig.

It's weird .

There are some influential fair comparisons of compiled languages, but for the most part my feeling is that people are moving from an extremely high level language like Python or JS, and then going to Rust to get performance, when any single compiled language would be fine, and for 90% of them, Go would have been the right choice (on backend or web-enabled systems apps), there was just a hurdle to get to most other compiled languages.

It's just Rust is somehow more accessible to them? Maybe it's that pointers and memory just was an inaccessible / overburdensom transition?

Rust is the only mainstream language with an ergonomic modern type system and features like exhaustive matching on sum types (AFAIK... maybe I'm forgetting one). Yes things like OCaml and Haskell exist but they are much less mainstream than Rust. I think that's a big part of the appeal.

In Go instead of having a value that can be one of two different types, you have to have two values one of which you set to the zero value. It feels prehistoric.

That strikes me as an incredibly niche (and probably transient) strength! But I will remember that.

This reads like a parody of Rust's fandom.

Going to lower level languages can be scary. What is 'fighting the borrow-checker' for some, may be 'guard rails' for others.

Not sure how much it weighs on the balance in those types of decisions. But Rust has safe concurrency. That's probably quite a big boost of web server quality if anything else.

Go's concurrency is unsafe? Rust's concurrency is automatically safe?

I am not saying you're wrong, I just don't find it any better than C++ concurrent code, you just have many different lock types that correspond to the borrow-checker's expectations, vs C++'s primitives / lock types.

Channels are nicer, but that's doable easily in C++ and native to Go.
