The biggest problem with public instructions is bullying and everything being targeted at minimum competence. Some 12 year old prodigy graduated college and high school at the same time because the pandemic and remote learning letting him zoom ahead at a ridiculous pace.[1]
Bullying is bad, but I definitely knew my role wasn't to be strong but rather academic. That line "nerds will be their boss" was my incentive. (Although I don't personally want to be a manager)
Sure it would be great to get rid of bullying, but I wonder if it's inherent in humans.
I'd focus on things we can control like that minimum competence problem you described.
