I could be wrong about this but my theory is that search engines are not very conversation oriented particularly google's. That is a majority of people want to have a "conversation" and that for the mast amount of non-techie people they would rather ask questions to a human-like entity instead of searching. It also may not be technical reasons but language reasons as well. On various social apps people can get trusted answers from their friends and family in their language. I have also noticed on StackOverflow/Quora there are an enormous amount of questions that could have been answered by a simple google query. A vast amount of these people through anecdotal observation are novice computer users and English is not their first language.
