The reason why I trust a doctor to operate on me is not that I know him personally or did a deep analysis of his past performance. It's the system around him that makes sure he will be personally responsible for any issues caused by the surgery.
An architect can charge a hefty premium if they commit to supervising the actual construction work and not just designing a building. The value the customer gets is a single point of contact in case of any issues, a single contract, a single entity responsible for the quality of the work.
Perhaps what most people sell is not as much the service they perform as the liability transfer. This might be the reason why AI will struggle to replace humans. Big Tech will never take responsibility for the actions of an LLM (see the hilarious clauses in Claude Code or Github Copilot ToS).
The optimistic vision is that this means the LLMs will usher in a future where rent seeking and responsibility avoidance are much more difficult than they are today. I'm looking forward to increased accountability in our society.
