I'm saying basic record keeping is the province of all to learn about in a democracy, and to hold back so severely when to comes to teaching anything about key technologies is fascist / royalist. If school is about making people more helpless and clueless than ever, then it's doing a good job by making "math class" so bereft of current content. If I were a Black Panther in the 60s (which I'm not, duh), I'd be teaching SQL in the basements of Chicago to ghetto kids for the AFSC. The FBI would be watching me. "Those skills are too dangerous in the hands of the underclass" said the memo from Hoover (played by DiCaprio in a recent film).

Yeah, you're right, I was compressing a lot. My education classes at St. Peters College in New Jersey did give me a sense, from the campus, that math teachers were high tailing it to the private sector, since their abilities were in demand. Turn a math teacher on to Python.... there I go again, Python not invented yet. Monty Python still new. And The Beatles a recent memory.
I always avoided anything BASIC -- except in that group home where I played homework games with foster kids and it came on their Commodore or whatever. APL was my first love but my bread and butter was said Ashton Tate's, dBase, later FoxPro, then Visual FoxPro, which took me into the cardiac surgery theater (CVOR) as a prodigy programmer, writing prototypes of stuff like GE's.
Good thing I was always interested in programming languages in general and studied Java, Scheme, Python in my search for good geometry software. However I did publish at article on Quadrays (cite Wikipedia) in FoxPro Advisor, before switching to Python more completely, lingering in VFP9 to help a genius engineer with his truck routing code pile (huge and in service). MSFT plans to officially pull the plug on VFP next year -- one of the chief danger's of a proprietary language is the proprietor.

But then I've been a full time high school teacher so they figured I could do the work.
Couldn't live on those wages (never tried). That wasn't a full time gig.

You're thinking of hardware, but should be thinking of faculty. You just said: why would you, for example, give up your income and lifestyle now, for that of a school teacher?
Are you going to retrain the existing math faculty?
They don't know enough CS to feel confidant they'll tell you. It wasn't their major after all, and if it had been, do you think they'd be there?
Think it through. Where would you get the teachers?
I think there are answers, but I don't think they're always obvious.
The UK by the way, is very seriously looking at jumping into that Rasberry Pi world in a bigger way. Do you follow that story? Python was big with One Laptop Per Child (OLPC) and is big with Raspberry Pi, so, as a Pythonic Math teacher, I feel I have a front row seat.
The UK truly is a different culture. The BBC made like a "national computer" awhile back, the BBC Micro. The BBC has no true counterpart in the US.

So if CS and Math go together like PB&J then why no SQL in high school hardly? Throw a dart at Chicago and take the nearest high school. "Do you teach any SQL in this building?" And repeat, with other cities and counties.
Nothing too fancy with the SQL, just a "how things work" approach linked to Venn Diagrams, the boolean type (WHERE clause conditions), the usual truth tables for if-then, and, or (contrapositive etc.). Logical fallacies. Logic gates. More history of the development of today's technology. Shoulda been doing that already. Today's content is so retro.
The math textbooks are not especially CS friendly. We've discussed this already, for years, on this very Forum.
We need hexadecimal and binary, even Base 64 for mime types sent via SMTP. What's SMTP? What's HTTP? What are mime types? The smart kids are left to study that on their own for the most part.
Adults need this stuff too and were left behind. Public television has failed us it seems. We never got much beyond Sesame Street and pedagogy. No andragogy, when it comes to A-Z, 0-12 (their adult equivalents).
I'm looking forward to when Robert Hansen's course is one of the offerings. Why not put your insights to good use?

Well that's good.
Don't forget you could do web site(s).
I'd like to get behind more YouTubes, with the BFI maybe?
I've been uploading more on my own recently, using VPython + iMovie. My detractor (you'll remember -- he joined us here) has chimed in with his comments.
