People who haven't gotten into habit of googling stuff in the last 20 years might not get into it at all anymore because of how search engines are gamed with SEO spam tactics nowadays
People are born everyday. Grandma may have had 20 years to figure it out, but kids these days won't have the opportunity to search the web and find information the way we did.
True, but the people born recently have existed with some kind of search capabilities, unlike grandma. They might not be able to optimize their queries like us, but they've still got ways to figure it out. They have habits, just different ones.
Grandma is the one who never bothered making the habit, because she was used to a time when no habit was possible.
