Rather than some conspiracy, my suspicion is that AI companies accidentally succeded in building a machine capable of hacking (some) people's brains. Not because it's superhumanly intelligent, or even has any agenda at all, but simply because LLMs are specifically tuned to generate the kind of language that is convincing to the "average person".

Managers and politicians might be especially susceptible to this, but there's also enough in the tech crowd who seem to have been hypnotized into becoming mindless enthusiasts for AI.
