Before you say things this patiently dumb you should probably wonder what question the researchers are actually interested in and why your average experience isn't sufficient proof.
It's "patently" and maybe understand the definition of "average" before using it.
Once you've figured out how to use language, explain why this is important and to who. Then maybe what the upshot will be. The fact that someone has proven something to be true doesn't make it important.
The comment I replied to made it sound like it's important to the field of AI. It is not. Almost zero serious researchers think LLMs all by themselves are "enough". People are working on all manner of models and systems incorporating all kinds of things "not LLM". Practically no one who actually works in AI reads this paper and changes anything, because it only proves something they already believed to be true and act accordingly.
