It's not that LLMs (I think that's what we are talking about when talking about AI) are not that useful. They are. But the most straightforward way to use them is to generate walls of text, which contain a lot of BS. In order to consume all this text and make sense of it, LLMs are used which reshuffle that BS into more BS but with less context. In the end, a human is presented with total BS that looks very plausible and if they don't critically evaluate it before forwarding to their higher-ups, they put their reputation at risk.
