Yes LLM's can beat humans in many tasks. But the jump from super spell checker to real AI is still huge.

It's like the 1960's where computers were beating chess players. (Not grand masters but they could beat regular people.) Because a computer could out think a regular human, people assumed that with more resources, we would have real AI in 25 year. That was Hal from 2001 Space Odyssey. It seemed very reasonable in 1968.
