People may be taught physics and biology, but most of the knowledge will wash through them once they finished their exams and got their grade.
The main problem with public schooling is that the system designers (learning-target criteria setters, curriculum designers, textbook publishers, etc.) don’t properly communicate the fact that surveying the field to build a mental map of it, is the goal of primary (and most secondary) education. So you get teachers, parents, and students all worrying about test scores that show that you don’t understand a particular idea, when the curriculum was never designed to communicate particular ideas, but only the structures containing them.
The problem is that even after years of working in the field you will likely be underpaid, and it won't be possible to find jobs in the field without a direct connection. Another problem is that if you want to go for a PhD to learn beyond that you will need to sit though years and years of useless classes that you have essentially already taken, just to check some boxes. I don't think anyone self motivated to learn things will sit though 6 years of useless classes to check some boxes or at the very least it will be terribly depressing wasting so much life.
At least that is my experience. The open materials for CS and AI are great though.
