For example, twenty years or so ago, I think the vast, vast majority of people in the US would agree that you don't have a right to privacy walking around a public street. However, once the Internet and Streetview came along, people had very different feelings about whether someone should be able to post a video they took of you on the Internet, for anyone across the world to see for all eternity, oh and we can also use facial recognition (just from public data and photos other people have posted) to fully identify you.
Privacy is just one example. I will personally say my opinions on free speech have also changed. Given how highly targeted, systematic and relentless well-funded misinformation campaigns can be, the old assumptions I had about free speech ("Given enough daylight, the majority of people will walk away from 'bad' ideas") I no longer believe to be true. I really don't have any idea what the "right" solution is, just that my views have changed.
The primary point is that wide scale, incredibly cheap data analysis (now being supercharged with AI) basically breaks all these fundamental assumptions and ideas society has, which is one reason why the world seems to be in such turmoil.
