It’s a dead-end technology that cannot be relied upon for anything serious
I'm sorry you are completely wrong. Do LLMs produce slop? Yes. Are LLMs useful? Also yes. The software industry, at least at the high end, is transforming rapidly because of this technology. The question of whether or not LLMs and other generative AI techniques along those lines are generally applicable is still an open one. But at least in some industries such as software it is certainly not a dead-end technology that cannot be relied upon for anything serious.
