People need to develop memetic immunity to AI flattery. It's exactly like how conspiracy sites on the Internet worked. A lot of people get one-shor in the beginning, but 10 years later mostly everyone understands that you can't just believe what you read on the Internet.
People have had several thousand years to develop immunity to flattery and yet here we are with a President where aides have to put his name in every paragraph of a memo to get him to read it.

At an individual level, we have a lot of psychological plasticity and can work to overcome our limitations. At societal scale, though, we are social primates and any system that takes advantage of natural social primate behavior is likely to succeed indefinitely.
You'd be surprised. I'm already sorry if I sound condescending, I just don't know how to rephrase this: please but please look around how effective is nowadays all that internet, dare to say more and more effective, in pushing "alternative truth" for the obvious goal of covering dirty businesses, wars, and even more crimes.
