I've been surprised how writing Rust becomes smooth with experience (mostly; it's still complex in some areas), however, there's more to a language than just the formal part.

Rust requires designing the memory management (ownership/lifetimes) of a program, which Golang doesn't, so even if/when the cognitive load is (hypothetically) equal, there's an additional, non-trivial demand. This is not something that everybody wants in a project (the given tradeoff may not be worth); for sure, if I had to introduce a language in my team only for tooling purposes (ie. small programs), Rust would not be the most productive choice IMO.

That's where I gravitate recently. I got a few more gray hairs learning and doing async Rust and I love the resulting program's speed and correctness.

But it's not easy to quickly prototype stuff with. Just recently I had to write no less than 7 small prototypes and I gave up on the second one, relearned Golang -- took me an hour -- and finished 3 prototypes in a day.

I tend to go all the way in languages so I can use them freely afterwards. But... In Rust's case I just can't justify the effort. Golang really helps you start off a project faster.

I'll still 100% Rust. I'm working on it every day. But indeed, let's use languages where they are at their best.
