Book PR, Fourth-and-One, the AI Knowledge Cliff, and LinkedIn WTF Moments

Something shifted this year and you can see it in the reactions. Not to the technology. To people talking about it. Rob shared a screenshot on LinkedIn. CFO. Friday night. Using CoWork in real time. The kind of moment where you have to stop yourself because you won't sleep otherwise. And that's what set someone off. Not hype. Not a prediction. Just… "this is happening." Apparently that's enough now. Rob calls it the knowledge cliff. AI knows three things. What's in the training. What it can pull from the web. And everything that only exists in your world. The first two feel almost the same. The third is where things break. That's where most of the frustration lives. If you haven't crossed that line yet, AI feels inconsistent. Impressive one minute, useless the next. If you have, it starts to look a lot more like real work getting done. You can see it in companies already changing how they plan and operate. You can see it in schools trying to figure out how to respond. And you can definitely see it in the comments, where people react to the exact same example like they're living in two different worlds. You can't really be smug about it. But the people who've crossed the cliff aren't waiting for consensus. They weren't a year ago either. This episode won't tell you what to think about AI but it will make it a lot harder to ignore what's already happening.
