I agree. Only speaking about the search engine I could imagine that in the future Google will still remain the dominant search engine. But search engines will be used less and less. Instead most people will use native apps and their respective search engines (facebook to search people, instagram to search pictures, netflix to search movies, yelp to search restaurants, etc.). It's a bit ironic that the biggest threat to Google's core business is a mobile operating system that was developed and pushed by itself. I'm still waiting for ads to appear in my native Google apps...
