No but we should still be level headed. It's like arguing that because 1) fire kills and 2) spreads, that the whole earth will thus be engulfed in fire and everyone will die.

If there's no real model behind this, I can argue just as well that a sufficiently intelligent AGI will be able to protect me from any harm because it's so smart and powerful.

And newsflash, if nothing changes, we're all going to die anyway. As it is, our existence is quite limited and it is only through constant creation of unnatural contraptions that we have managed to improve our quality of life.
