I understand, but as you say, it is only true for certain topics, however, sadly, internet as a general is full of misinformation, disinformation, toxicity, and plain outright nonsense.
I am not sure it is worth repeating, but as I said, the notion that "internet is scary smart" is only true for certain groups and topics, but not internet as general. That does not mean there is no "smart" forums or smart people on the internet, nor I made any remarks about YC News.
