Not at all. I've merely listed three attributes which people might (wrongly) associate with a computer, but which are not actually features of a computer at all, and in any case are far from the exhaustive story on the Supreme Being."A Supreme Being" with no need for distractions, with perfect intent, who never fails.
You've described the perfect computer (which is what some suggest the universe 'is').
Computers only are impervious to "distraction" because it's not sentient, not because it is perfectly interesting in itself. As for intent, it has none, just as it has no volition: computers don't *want* anything. And, of course, computers can fail; they do all the time.
As for additional qualities of the Supreme Being I did not include in those three, there are things like will, creativity, intention, character, purpose....and so on. All of those are features of God too, but not at all of computers. And computers are also contingent items, not necessary entities. But above all, God is a "Person"; not in a limited way analogical to our own personhood, but rather in a prototypical way, as exceeding our personhood.
In short, He's more of a "person" than we are. We're the faint copies. He's the Original. We are "made in the image of God," as the Bible says; He is not merely made in ours.
