My teacher friends are really worried about the AI era

I had a few drinks with some high school teacher friends the other day..
I didn't realize it myself, but they said AI tools can now solve CSAT (Suneung) questions almost perfectly..
They were all saying in unison that it feels like we truly need to completely reform the educational paradigm at this point.
They mentioned they aren't sure if sitting down for 50 minutes to teach bits and pieces of information is even appropriate in this AI era, where vast amounts of knowledge can be acquired instantly.
