Agreed, human equivalent AI is probably several hundreds of years off, at best. but we don't need anything that sophisticated to trigger an "overlords" scenario.

I'm picturing something like a very good legal AI, being abused by a foreign state's hackers to ensure the incarceration of political opponents, in preparation for a coup. We're not far off from that being a plausible scenario now, but if we all had the benefit of a personal legal AI, or access to a collective legal AI, then it would be a lot harder for anyone to use the legal system against an individual opponent, as a simple weapon.
