Just for the sake of fun !!!
Google can't translate.
Google can't do mail.
Google can't do blogs.
Google doesn't understand things.
Google can't do news.
Google can't do ads.
Google can't do search.
Google can't do browser sync.
Google also can't discover new things, understand your queries, build communities, pass Turing test, bring world peace...
But still, Google is the BEST !!
