Whoops, yes. Well I hope the point came across anyway.

it's funny that as a non-native speaker, I have to check with Gemini about how "cannot overstate" is used

I also asked Gemini whether we express ourselves that way in my mother tongue (Mandarin), and yes, we do, but it came off as being too formal way of speaking. We don't normally use it (I'm not from China/Taiwan though)
