I would expect wikipedias to be more accurate than teachers.

I am a software engineer who spends his life showing people the origional sources of information to help them unpick collective repeated misunderstandings. That takes me, with more experience that my team combined to do that.

teachers have experience of teaching - not possessing knowledge or the practises of sifting, applying and validating their hypothesis aroudn the veracity of information.

Most curriculums are out of date in ways that don't matter all that much. But i still rekon wikipedia is still more up to date than them.
