Funny you say that, I just randomly watched Terminator Salvation on TV a few days ago (had never watched any after the first two).
When I said current tech, I meant, if current tech is enough for some of us to save their asses from these natural disasters, then in the future it will likely be as well - implying tech would likely not get worse, though it can because although knowledge will usually increase (and knowledge can be lost as well, but keeping it simple for now), materials and energy available to produce the tech can decrease.
Nuclear and biological weapons are definitely a threat. A.I. maybe, I think we'll just integrate with machines, so there won't be a machines vs humans thing. All in all, I find complete extinction unlikely.
