That's not what he's saying at all, though. What he's saying is that he thinks the current techniques for AI (e.g., LLMs) are near the limits of what you can achieve with such techniques and are thus a dead-end for future research; also consequently, hyperventilation about AI superintelligence and the like is extremely irresponsible. It's actually a substantial critique of AI today in its actual details, albeit one modulated by popular press reporting that's dumbing it down for popular consumption.
