IF people understood this study, Nvidia would drop, sharply.

BREAKING: Reliability, which I have been harping on here since 2019, continues to be deep problem, even with the latest models.
A new @Princeton review below offers a taxonomy of some of the many ways in which reliability continues to haunt LLMs seven years and a trillion dollars later.
Crucially, “many models lack metacognition about their own reliability”. They don’t know what they don’t know.
Forget about AGI if you can’t solve that problem.
It’s past time to rethink the whole LLM paradigm.Show More

One Sentence Summary
Gary Marcus asserts that if the public understood the deep reliability problems of large language models, as highlighted by a new Princeton review, Nvidia's stock would drop sharply.
Summary
This tweet from Gary Marcus, quoting his own earlier post, draws a direct and provocative link between the persistent reliability issues in large language models (LLMs) and the market valuation of AI hardware giants like Nvidia. The quoted tweet emphasizes that even the latest models suffer from fundamental reliability problems, particularly a lack of 'metacognition'—they don't know what they don't know. Marcus argues that this foundational flaw, seven years and a trillion dollars into LLM development, necessitates a complete rethinking of the LLM paradigm and suggests that a widespread understanding of this issue would have significant financial repercussions for companies heavily invested in the current AI infrastructure.
