I find the source collating of Wikipedia helpful for recent events. That's when you're going to get most editor interest to improve the page and readers to consume it.

There clearly is editor and reader interest in making decent quality articles on major current events. Yes they may contain errors that the history book on topic won't contain, but I still think it's worth having. Just mind the things to avoid listed in WP:NOTNEWS and I think we will be fine
And I don't think everything will ever be covered in a book. There is not an infinite amount of scholars studying every random significant event. And those will probably use the same news articles as one of their sources anyway.
Yeah basing articles on scholarly books is good, but not every topic will be covered and https://en.wikipedia.org/wiki/Wikipedia%3AThe_deadline_is_no...
