I find Go bizarre... 90% of the code written in it seems to consist of checking for errors and passing them around. And yet, every time I've had to interoperate with somebody's Go code, it falls apart immediately because of significant processing errors that it seems like somebody should've caught, like a null-pointer dereference, or a wrong lookup into a map, or a (de)serialization error.
_Every time_ the programmer responsible seems blissfully unaware of the possibility of said error and I need to provide a test case for them to reproduce it. Their mental model of the code they think they wrote is wrong compared to the actual code.
The culprit is usually something like an `interface{}`, granted, which people then excuse as being un-Go-like... but if all the language's supposed ease and robustness fails as soon as it encounters anything outside of its own ecosystem, then it's not worth much. All the busywork around errors starts to look like a cargo cult to make the juniors feel like they're accomplishing things when they're just glueing things together.
No other language I've seen has it so bad. Rust is particularly good in this area, and seems to view it as its own responsibility to interoperate cleanly, providing sane and powerful ways to opt-in/out of Rust's semantics at the edges. Even TypeScript makes it easy to partially or gradually type when you need to, and this seems much safer in practice to me.
