Important and basic are not the same. The original post claimed 'one's ability to use search engines is a basic instrumental rationality skill.' To lack something that is basic is to not be able to move forward. I make the counter-claim lack of any internet skill is no detriment to rationality. I add that claiming internet use is a basic rationality skill suggests a lack of consideration of those places where the internet is filtered or more difficult to access. I am not saying the original post or its author is racist, rude, insensitive, mean or foolish. I am saying the original post's author appears to have not considered those places where the internet is filtered or more difficult to access. Which is plenty of people.
