The technology for human intelligence? Any technology would be always very different from human intelligence. What you probably are referring to is AGI, that is defined as artificial general intelligence, which is an “intelligent” agent that doesn’t excel in anything, but is able to handle a huge variety of scenarios and tasks, such as humans.
LLM are specialized models to generate fluent text, but very different from autocompletes because can work with concepts, semantics and (pretty surprisingly) with rather complex logic.
As oversimplification even humans are fancy autocomplete. They are just different, as LLMs are different.
