I have no idea. You don't have any idea either or you'd have told me by now. You are just saying that magic will happen and the world will be ours. That's the problem with risks from AI.

We have plenty of ideas. Yvain posted a Discussion thread filled with ideas how. "Alternate history" is an old sub-genre dating back at least to Mark Twain (who makes many concrete suggestions about how his Connecticut yankee would do something similar).

But what's the point? See my reply to Bugmaster - it's impossible or would defeat the point of the discussion to actually execute the strategies, and anything short of execution is vulnerable to 'that's magic!11!!1'

The AI can't acquire the resources that are necessary to acquire resources in the first place. It might figure out that it will need to pursue various strategies or build nanoassemblers, but how does it do that?

By reading the many discussions of what could go wrong and implementing whatever is easiest, like hacking computers. Oh the irony!
