@llewelly @futurebird @nottrobin @shiri A big factor is also that if you promise people a solution to their problems they will want to believe it.
Until recently, I worked in a nonprofit in health and I encountered sooo many good people that talk about AI as a way out of personnel shortage with genuine hope in their eyes. You can tell them about the problems all day long, but accepting that we can't trust ChatGPT with our health would mean that their vision of the future goes back to bleak, so they will dismiss anything but optimism.
There are definitely plenty of executives knowingly selling bullshit for profit, but far more people just want to believe that the miracle machine actually works.
