Try it out. Ask "Do you know who Emplabert Kloopermberg is?" and ChatGPT/Gemini literally responded with "I don't know".

You, on the other hand, truly have never encountered any information about Thai grammar or (surprisingly) hot to build a jet turbine. (I can explain in general terms how to build one from just watching Discovery channel)

The difference is that the models actually have some information on those topics.
