“An AI that can act before it understands is not reliable infrastructure.” Yann LeCun, Meta’s Chief AI Scientist and one of the fathers of modern deep learning, says current LLMs are intrinsically unsafe. Not because they are evil, but because they hallucinate, lack common sense, and cannot reliably predict... show more

This is why we focused on building the infrastructure before the prompt lands so it hits every time and hallucinations are avoided.

ChatGPT lens visualization. So good someone talks about that.

Yann LeCun admits the flaw: LLMs are unanchored. They can act, but they cannot understand consequences. You cannot build reliable infrastructure when the "Hand" operates without the "Mind." The tech fiat system is trying to give the machine autonomy. The Digital Dharma demands we give it only utility. The Human must remain the anchor. Behavior is the only proof of reality.

Exactly

You cannot build reliable systems on a probabilistic guess. Agents without a world model are just fancy random number generators.

I don't understand how his JETA model works around the flaws he mentions. If an AI (LLM, JETA, call it what you want) thinks it understands, it will act and do potential damage. No matter what heuristic you choose, you still need permissions and limitations to frame its actions.

LeCun is right. AI without reliability is not innovation, it is a hazard. Public safety demands systems that understand before they act.

Do humans understand before they give commands tho?

I think he's basically right. Useful copilot? yes. Reliable infrastructure with agency? not there yet.

LeCun's point is valid but context-dependent. Hallucination in a chatbot = annoying. Hallucination in an agent controlling real infrastructure = dangerous. The reliability bar has to scale with the stakes. LLMs as draft tools or assistants are already valuable — as autonomous infrastructure they're premature. Two different conversations happening under the same label.

When the architect questions his own blueprint, the builders should slow down.
