Your professors generally don’t make stuff up if they don’t know something. Your professors are also more likely to catch on if something doesn’t make sense - unlike ChatGPT which can’t seem to reason effectively because most of the time it doesn’t know what’s it’s talking about.*

* Maybe it has the ability to reason, maybe not. Maybe it just needs more information - after all it’s trying to model reality with just the words used to describe it. Or maybe it really can’t reason at all, a limitation of its algorithm, and has to rely on having arguments/explanations already memorised - which seems to be mostly what it does now. Either way so far it hasn’t demonstrated that it’s all that good at reasoning.
