I don't think that we read the same article. In particular, if over 85% of Google's revenue is from ads, then there's no way that the rest of the business can carry Google, nor that any particular single department could survive on its own. Youtube has never been profitable, and their acquisition by Google is likely what saved them from running out of cash. If there comes a day beyond online advertising as we know it, then Google will collapse; Google cannot compete effectively outside the Web. You are almost right, but didn't look high enough. Alphabet, the big holding company at the top, can survive Google's collapse, and Alphabet is diversified.
