Is Cloud Game Streaming Services the Future of Gaming?

For one year now, I have testing the new streeming service of nvideo for gaming geforce now and it's amazing what they can already do. For someone with a Mac that are always restricted on the games sector this open a all new world of possibilities. With a great catalog of games and every month updating being able to play steam games, ubisoft, blizzard and many more.

I am curious to know your opinion regarding this topic and if you believe this is the future of gaming. Also share if you already try any service like this from liquidsky, geforce now or any other and your thoughts on it.
