Hallucinations in code are the least dangerous form of LLM mistakes

Large Language Models (LLMs) producing hallucinated code methods is considered a minor issue since compiler errors immediately expose these mistakes, unlike prose hallucinations which require careful fact-checking. The author emphasizes that manual testing and code review remain essential skills, as LLM-generated code's professional appearance can create false confidence.

Gödel's theorem debunks the most important AI myth. AI will not be conscious | Roger Penrose (Nobel)

Roger Penrose argues that AI systems are computational tools lacking true consciousness, which he believes requires non-computable physics beyond current quantum mechanics. He emphasizes that intelligence inherently involves consciousness, making the term 'artificial intelligence' misleading, and suggests that current AI systems process data without genuine understanding.

Pentagon guts national security program that harnessed social science

The Department of Defense is terminating numerous grants under the Minerva Research Initiative, which funds social science research for national security. Dozens of researchers studying topics like violent extremism, disinformation, and climate change threats have had their funding cut, signaling a possible end to the 15-year-old program. The initiative's $46.8 million funding supported crucial research on security challenges, from AI applications to drug cartels.

Geothermal Power Is a Climate Moon Shot Beneath Our Feet

Scientists and companies are exploring geothermal energy as a potential clean, unlimited power source that could meet global energy needs. The FORGE project in Utah is developing techniques to harvest underground heat through enhanced geothermal systems, while companies like Quaise and GA Drilling are pursuing deeper drilling technologies.
