100% the opposite. LLMs lack high level creativity, wisdom and taste. Being a generalist is how you build these.

For example, there's a common core to music, art, food, writing, etc that you don't see until you've gotten good at 3+ aesthetic fields. There are common patterns in different academic disciplines and activities that can supercharge your priors and help you make better decisions.

LLMs can "see" these these connections if explicitly prompted with domains and details, but they don't seem to reason with them in mind or lean on them by default. On the other hand, LLMs are being aggressively RL'd by the top 10% of various fields, so single field expertise by some of the best in the world is 100% baked in and the default.
