I recommend reading Yuval Noah Harari's Nexus for a deep discussion around this.
He makes the point that what makes this AI age much more dangerous for mass surveillance isn't just the collection of data, which has indeed been possible for a while, but the new ability to have AI sift through that enormous volume of information, an ability which until recently has not been possible in a meaningful way without a ton of manual work to support it.
Older attempts at mass control of a population already involved mass surveillance, even in a large amount of detail, but even when capturing in detail all citizens' activities, there were just not enough people around to be able to dig through that and analyze it. This has been somewhat true even with the help of computers, though computers have certainly already been making this easier.
But now you can just give all that data to an AI with your instructions, and it'll apply some sort of "judgement" on your behalf, completely autonomously, and even perform actions against those folks it finds, again autonomously, without needing to manually build a whole infrastructure to do that with manual rules. That's a very meaningful upgrade for someone wanting to control a population.
like saying kids having internet-connected devices with built-in cameras doesn't increase the probability of sexting, they could do the same with film cameras and a fax machine
