I agree, but there's also teachers who give out wrong information too. Often it's when the teacher doesn't have a deep understanding of the topic and are just repeating what they've heard (or misheard) and they will typically compound the issue by not allowing curious questioning.

There's also the issue that modern teachers are more like exam coaches rather than trying to actually teach kids.

Teachers earned their titles, they had to prove repeatedly that they are fit for a job that includes proving that you can learn things, that you have a logical thinking, that you are a decent enough person and that you have developped the social skills to lead a bunch of volcanic young people, taking the best paths to their grow and benefit.

AI is just the weird guy that sneaked its way in, without any reference. That is know to lie often in a very convincing way, specially when it does not have an answer, and that can be persuaded to include a lot of weird random ideas or fake facts in their classes.
