"Everyone knows this", "People don't really want this".
No they don't. Phrasing like this is typical for people who want to persuade others that their opinions are somehow widely shared. It's a cheap rhetorical trick. Populists use this all the time. That doesn't make it any more true.
Some people might want that to be true (including you apparently). But most people haven't got a clue when they are using AI or aren't using AI and can't articulate what it is and are perpetually confused about anything technical.
You are probably right about everyone getting a bit worn out about everybody blabbing about the topic. That's because most of those people don't make any sense. And of course there are a lot of products that are pretty bad that advertise their supposed AI qualities. So understandably, people are a bit put off by that.
If you read a lot of stuff that uses phrasing like you just used, you are likely suffering from confirmation bias. That's a thing that causes people to genuinely believe they are right about something because they unconsciously avoid consuming information that disagrees with their views and seek out peers and sources of information that confirm them. Everything they see and hear confirms them in their biases. A lot of media sources actually prey on this by feeding lots of (AI generated, of course) content that deliberately manipulates groups like this.
All this study really shows is that people are tired of vague AI features that never really deliver on their promises. But they happily read a lot of stuff on twitter, linkedin, youtube, etc. blissfully unaware that they are consuming a lot of generated content that is fed to them by an AI that decides what they should consume next. All those supposed AI haters are hopelessly addicted to things like Tik Tok, Instagram, and what not.
The trick with selling AI is to not talk about it. People love magic. Just don't tell them how it works.
