One OS is not going to rule the entire tech industry. For one that is a monoply, and it is not allowable. Two, you don't want one company having complete control over everyone.
Sony can stick around as long as they continue to broaden the PlayStation OS functionality. If they start to bring in more non gaming apps, and change to a more Apple like closed ecosystem, than the current extreamly limited closed ecosystem, then PlayStation will not only stick around, but be one of the largest players in home and mobile computing.
The future is going to be based around OS and cloud wars. I think it will be Mircosoft vs Sony vs Google vs Apple, with Samsung having a chance if they start to transition fully to Tizen. These OS's will have hardware ecosystems built around them that range from slabphones to specialty phones, tablets to laptops, and consoles/set top boxes to PC's.
Having competition drives tech forward, and keeps everyone honest. That is not going to change in the next 20 years. The only surprise may come in the form of a new entrant. Otherwise, it is going to be competition as normal.
Stop hate, let others live the life they were given. Everyone has their problems, and no one should have to feel ashamed for the way they were born. Be proud of who you are, encourage others to be proud of themselves. Learn, research, absorb everything around you. Nothing is meaningless, a purpose is placed on everything no matter how you perceive it. Discover how to love, and share that love with everything that you encounter. Help make existence a beautiful thing.
