Sure, drop into C sometimes. But telling beginners to start there is mean.

I spent a lot of time in assembler too, and yes it has benefits for learning. Im also not recommending a high level toy like Logo.

I don't know if I understand that. Everyone was also a beginner at some point. I was a beginner at both C and Unix when I learned them together. I wrote a lot of bad C code before I got good at it.

I also say hand-in-hand as a bidirectional thing. I wouldn't suggest learning C without learning about Unix too. And I say that as someone who has worked extensively outside of Unix-like platforms.

Indeed. All the foundational common ground between all languages in Unix is made for C. I'm talking about the system call interface. All general purpose languages will have a wrapper for this interface, but the main documentation is made for C.

Besides that, libraries tend to be made in C as well. That's because if it's in C, it's easy to make it available for other languages. Most general purpose languages will have some type of "foreign function interface" to call on C code. That means that the main documentation for these libraries will be for C as well.
