Grok has the biggest advantage in current events knowledge because it's integrated with X, which enough people still use even though it isn't Twitter.

Hm, when compared to all the information people with android devices share with google, or those with gmail, ..

Google wouldn't give Gemini direct access to everyone's Gmail. It would carry far too much risk of being exposed. X can, because tweets are public.

But google can give gemini access to summaries of all the avaiable information google has, including what people look for right now and where and how long.
