Average school system has been lacking for a very long time, overhauling it to focus on kids current interests, while sneaking in the other stuff, might now be possible and cheaper to realize with our new tech.
Reminder that the internet was created to be live and a indestructible means of reaching one and another, none of what you wrote can meaningfully do what you think it would.
Failing in parenting and lobbied politicians (regulatory capture) on the other side.
Have more success with asking for a detailed workflow print then a d2/mermaid output.
No problems with creating a ASCI diagram either and using that for a manual d2 can be done fast enough.
