First you'd have to come up with a commonly accepted definition. By some ~16 years old definitions from famous experts in the field, we've already achieved it. By today's definition (of the same expert) we haven't. There are people today that think we have it. There are people today that think we'll never have it. It's such a loaded term / topic.

Also, regarding LLMs, 2 years ago another famous expert in the field was adamant that LLMs can't plan, can't do math and they can't work at long contexts. Obviously they can do all of that now. So, really, no one knows.
