No tool is frictionless. You can prove that easily enough by slicing vegetables with a hammer. Tools create a river of frictionlessness, buttressed with steep banks of friction.
The specific ways in which LLMs are frictionless encourage slop. The frictions of LLMs discourage editing & fact checks.
It's interesting to contrast with the original vision for the computer. The LLM doesn't aim to be a "bicycle for the mind" (Jobs) nor extend senses and reach (MCLuhan) but displace cognition. Instead of a machine that does what you tell it, it's a machine that tells.
