Yes.
I have only one of their services that I do not see replaced any time soon. YouTube. What they do there is impressive, and very, very hard to replicate.
Not a fan of YouTube, don't get me wrong. But I see nothing comparable out there (maybe AWS, but they just run some infrastructure orchestration).
Google will kill YouTube long before anybody else is able to pull off the same stunt.
Or is there a service comparable for video streaming?
