I say AMEN to that! Let's have a big cheer for rationality! If you (duly) don't like the idea of an "almighty" God, then, by definiton, you don't like the idea of an "almighty" AI Power. Unless your logic module is flawed, that is. If the AI says "you should die because it serves the Ultimate Good", the correct answer is "fuck you, asshole".
How do you want to use (non-sentient, I assume) AI to become immortal, btw?
