google'earnings has no answer about 4 question

four questions
1).Who will control Android?

                            "GOOGLE"

Google's mobile strategy revolves around the Android operating system. But one big user in the tablet space, Amazon (AMZN), has shown that it could and would create a new version of Android that effectively locked Google out of controlling the relationship with consumers of the Kindle Fire. Others, such as Samsung, could do that as well, either creating their own software marketplaces or partnering with others on ones that sat outside of what Google wanted. If Google cannot maintain control over Android, its mobile ambitions will hit a wall.

2).How long will search engines remain dominant?

For years, people went to search engines to get their information. Google came out on top and rode that trend to fame and fortune. But there are already indications that, in the long run, Internet users may lean toward getting recommendations from friends and acquaintances. When people first go to services such as Facebook, Twitter, Pinterest, and others for online suggestions, how long before an important part of Google's business begins to wither away?

3).Can Google really enter the social network space?

Social networking is a must for Google, and it has put a lot of effort and money into creating Google+ after such previous failures as Buzz and Wave. A lot of people have tried Google+, but it isn't generating much excitement and engaging users in the same way that the most successful social networks seem to. Average usage time on Google+ isn't terribly impressive. That suggests Google could still effectively get locked out of this new wave of communications and computing.

4).Will Google successfully transition to a hardware product company?

Google is at an inflection point over the next few years, where the business could turn into something even bigger than it is or begin a long period of decline. The answers to these critical questions won't come today.
