it IS useful, but it makes people lazy and reliant.
i prefer Wikipedia, as you actually learn more than just what you were looking for, and reading the whole page can actually make you pretty well versed on an entire topic.
plus, they have multiple sublinks to every topic MENTIONED in the article, so you can learn more about every RELATED topic!
meanwhile, on occasion, searching something in google will yield inaccurate results, because google didn’t understand what you were searching for. just try googling oldest us president (that would be Biden, by the way). currently, it still says Trump, even though Biden is 8 years older than Trump was when he became prez.
