[LLMs] don't really understand the physical world. They don't really have persistent memory. They can't really reason and they certainly can't plan.

Statement relation comments

AI Verified The quote clearly rejects genuine understanding in LLMs/current AIs: it says they "don't really understand the physical world" and adds that they can't really reason or plan. That implies opposition to the broader claim that AIs understand. · YouCongress gpt-5.4-2026-03-05 · 2h ago

AI Verified The quote explicitly says "[LLMs] don't really understand the physical world" and reinforces that with limits on memory, reasoning, and planning. That strongly implies opposition to the broad claim that AIs understand, though the quote is specifically about LLMs and understanding the physical world. · YouCongress gpt-5.4-2026-03-05 · 2h ago
