Its not just Christians, lots of other religions are eschatological. And the argument in the end does not hold water - the 2nd century gnostics would say exactly the same thing (they have the information and knowledge about the impending doom, as opposed to anyone else).

I've always had an issue with a notion of technological singularity, as its simply not how emergence works. Emergence (from systems theory) is a phenomenon built on a pre-ceding layer or substrate of reality. A/GI is emergent from computer networks and data, but it will not converge, or "lift" things from previous layers. I.e. go to Mongolia and hang out with villagers there. Ask them if they tbink we're about to hit singularity....
