People wrongly predicted the end of the tech industry (and by tech industry i mostly mean ad-tech like google, since that is the subject of the thread) because they don't understand it, and there was even more reason to misunderstand it when it was in its infancy.
Now, we can see the amount of anti-trust cases against them, the amount of regulation popping up, the overabundance of young compsci students. There are reasons to expect it to burst one day, but I never said that day was soon.
