1. AI Infrastructure and Open-Source Leadership Debate

1. Yann LeCun endorses IBM CEO's view that the math behind AI infrastructure buildouts doesn't add up, as massive data center investments may not match real demand, potentially leading to significant writedowns. — via 1

2. LeCun argues that open-source AI leadership should come before general AI leadership, as open source accelerates national tech ecosystems. He contrasts US and China open-source timelines and notes that OpenAI and Google started with open science. — via 1

3. Citing Nobel laureate Robert Shiller, LeCun warns against AI panic, noting that economic depressions are driven by self-fulfilling fear. He also points to an Arizona State University paper that disproves the notion that LLM step-by-step plans reflect genuine reasoning, calling them reasoning hallucinations. — via 1 2
