The problem with complex languages is that while you can choose to eschew complexity in the code you write, you very often have to deal with the complexity in the libraries you use. So in languages like Rust and C++ you tend to have a high degree of complexity (at least by way of high degrees of abstraction) in the standard library and the wider ecosystem because abstraction (and thus complexity) are valued and idiomatic in their respective ecosystems—it makes it very hard to opt out of. For example, at least for a good while, there wasn’t a great JSON parser library except serde which is immensely complex and I would spend a lot of time troubleshooting errors in the macro expansions for things that would Just Work in Go’s encoding/json (of course, there are plenty of legitimate grievances with encoding/json, but these are mostly orthogonal to the simplicity/complexity discussion).
