It's not (going to be) as blatant and obvious as popular media are portraying either. The robot overlords won't be tentacled red-glowy-eyed things, but friendly helpers.
And it won't be sudden. People will be eased into it over time. And not even that much time; we went from nothing to basically having one or more permanent on tracking devices on ourselves at all time within just a decade or two, and we freely give permission for companies to track us because they (say they) offer convenience in return.
It's not an oppressive regime, it's companies. Which funnel money to the regime so they get a free pass on doing whatever they like.
