>What I mean is, the way I was taught maths and science in general was with a feeling of “look we basically know everything just learn this and you’ll be fine”.
That's pretty much how anything is taught in high school (and even most undergraduate programs). It's considered confusing to teach students that a lot of what we "know" is known to be incomplete and will change. I've kept some of my textbooks on immunology and other biomedical topics from the 1990s and parts of them are basically unrecognizable to what we are working on today. Sure, the basics haven't changed but the details certainly have.
