Maybe, but it's not possible to critically evaluate everything you see and read. For sure most people don't, and probably no one does all the time. So if before 10% of information was lies and manipulation, most of the information was still good, or at least something that a real person thought was good. Now, or soon, anything you read or watch has a 99% chance of being generated by someone who wants to manipulate you, because those who want to manipulate have something to gain from it, and are willing to spend more money to do it than those who want to share the truth.
