I didn't see your reply until now but "AI" is correctly describing the phenomenon. Most definitions for "artifice" converge around the idea of deception or insincerity.

The term "machine learning" also distinguishes itself from the organic process by authentic intelligence.

In other words, inferring "machine intelligence" is less correct than "artificial intelligence". By definition LLMs are machines pretending to think and they do it well enough to have a writing style.
