Hey, Eztosin
I'm trying to gather a team of people to build an AI powered operating system (imagine being able to give your computer commands in plain English and have it interpret and execute them). You seem to know a lot about OS development and so I was wondering if you'd be willing to help me create one. If you are, please let me know (my email is erockthefrog@gmail.com).

  1. A much better history of C is here.
  2. Historically, C compilers did not produce 0s and 1s; they generated assembly source code for the host CPU. The assember then assembled that into 0s and 1s. Indeed, the reason C compilers produce a.out by default is because the a stands for “assembler.”
  3. Everything you said can also be said of C++.
  4. The Wikipedia page for C does a much more thorough job of describing C. What does your post bring to the table?
