C is the hardware language N°1 of the high-level languages. If you actually want to know and control what happens in the machine, you write in C. Rust, C++ and all the other abstractions are for people who do not understand how computers and computer memory work.
Edit: grammar
I’ve written programs in C. I’ve written programs in assembly, for x86 and for microcontrollers. I’ve designed digital logic and programmed it into an FPGA. I’ve built digital logic circuits with transistors.
I’ll still take Go over C any day of the week. If I’m doing embedded, I’ll use TinyGo.
Why? I see no reason to go through the hassle of learning yet another language when Go serves my purposes perfectly and I’m happy with it.
