infinite being, eternal, supernatural and existing by itself, necessary cause and ultimate end of all that exists
As the Portuguese dictionary says, the problem of calling God is the connection with spirituality, it is even strange to call a machine of God.
Now, we can put Google as an example. They know what you do, where you are, what you like and what you do not want anyone to know, and he's everywhere listening to you. The only way to not be under Google's vision is to stop using a cell phone, computer and living a boring life so carefully that you would have to have to not be watched.
It's funny the relationship. According to the Bible (I am an atheist), the man departed from God in Babylon (cities).
But can we call Google God? If Google does not have a backup of its core scattered through space and other planets, I think the human can still destroy the world and bring Google together. But following rational ideology, he is closer to being God than anything on earth, including us.
