What would a concrete AI takeover plan look like?

You can smell a chess bot by how quickly they change plans^[1]. Human players act like they have a couple of attack strategies in mind and stick with them. Chess bots change tacks constantly, one move looking like they're moving towards this goal and next move switching to something totally different.

I'm guessing this it how it would be with real-world takeover. Human need a simple grand strategy they can coordinate around ("An amphibious invasion of northern France"). AIs, even very weak ones^[2], have far more working memory and excel at breadth. Their plan could be 1000 plans at once.

   Or so I've been informed. I don't play chess.

   The scope of this comment is weak AIs that could still pose a threat to humanity, not superintelligent ones where you just lose.
