Personally, I don't think CS should be a core subject in primary schools. I think it'd be better to have some kind of technology competency subject, to help teach basic use, problem solving, security and privacy practices, and whatnot. A bit of programming and the core concepts of logical thinking and algorithms wouldn't be a bad idea, but I think most students wouldn't actually need to know CS.

If they want to address job demand, I feel it'd be better to increase teacher pay to get better CS teachers, so there'd be a few _good_ CS graduates, rather than many _average_ CS grads.

They could cover: bash and typical shell tools, make with markup languages, octave, spreadsheet scripting, R, Julia, and possibly version control.

That does a good job of supporting the fancier math and science classes, both there and in college, and could actually be useful in jobs that aren't too obscure.
