This is an entitled take. The usefulness of a thing has nothing to do with how easily communicable it is. That is the whole premise of specialization and becoming an expert. People go in-depth on things so they can say “trust me on this” and so you don’t have to. You are advocating for a tyranny of the illiterate.

Also, this reads like you didn’t like math classes. That sucks, but it’s no basis for societal organization

I am advocating for effective communications, it is not as if knowledge once understood remains difficult. To communicate and convey understanding is good, and to withhold understanding is tyranny.
