> the "deep expertise" OP laments was actually deeply inconvenient to many people

This reminds me of the Upton Sinclair quote: “It is difficult to get a man to understand something when his salary depends upon his not understanding it.”

LLMs feel threatening to anyone who had an edge by knowing how to navigate domains with a lot of weird and complex behavior. It’s nice to feel like businesses need you if they want to solve a problem. It’s scary when a cheaper solution arrives that does 70% of that deep knowledge navigation at 1% of the cost.
