Excuse me? Step by step wasn't paper-worthy? Hard disagree.
LLM research is currently in its infancy, because they are no older than a few years old. And a research field in its infancy is bound to have a few noteworthy "no sh*t, Sherlock" papers that would be obvious from hindsight.
The fact is, LLMs are a higher-order construct in machine learning, much like a fish is higher-order than a simple cellular colony. Lower-order ML constructs do not demonstrate emergent capabilities like step by step, stream of consciousness thinking, and so on.
Academics should be less jaded and approach the field with beginner's eyes. Because we are all beginners here.
