You're probably right that for trivial examples C is, in principle, the simplest to learn and understand. But in reality, non-trivial C projects come with complex build systems, makefiles, macros, endless compiler flags... I've found it pretty hard to, for example, fork a moderately-sized C project and modify it. Hell sometimes even building it is a challenge when you don't understand make/build system errors and how to set up and configure C projects.
Go, however, i could just get up and running. Simple to use modules, simple to import dependencies, simple to build projects, great centralized documentation. Now granted do i fully understand all the nuances of things like pointer receivers and generics? No, but i don't really understand memory allocation in C either to be quite honest, and I've spent more time trying to understand C in my life than i have Go (please understand: extremely little in both cases)
Rust does seem similarly impenetrable honestly, except that it seems much easier to build and manage Rust projects. But I definitely can't even just read Rust code and get it the way i can Go (or even C)
