Awareness of death may partly explain why people would keep competing for status even if AI made necessities plentiful, physicist Brian Greene argued, drawing on Ernest Becker. He said people could change but wasn't optimistic.
Brian Greene doubts today's chatbots such as ChatGPT or Claude have feelings, but sees no fundamental barrier to conscious machines and expects people may come to treat them as conscious without settling whether they feel anything.
Brian Greene argues AI could make Newton-scale discoveries, expecting it to excel at exploring options and linking fields while humans, for now, lead in inventing new frameworks. He sees collaboration reshaping physicists' role.
Physicist Brian Greene argued with an AI on The Diary of a CEO that self-improving AI may approach a ceiling set by its architecture, not accelerate indefinitely—while warning that if no ceiling exists, gains could outpace human oversight.
Ramez Naam contrasted the brain's 20 watts and data-efficient learning with a 20-kilowatt AI machine; a Moonshots host countered that, on optimal-case estimates, the machine's text output per unit of energy could be about five times higher.
Energy investor Ramez Naam argued that physics and engineering, not regulation, remain the barriers to Helion's Microsoft power deal. Meeting its 2028 target needs whole-plant energy gain, durable parts and affordable electricity.
Ramez Naam says AI demand could finance multi-plant nuclear orders that may lower costs, but doubts small reactors can supply power within the five-year window he sees as predictable, and expects their roughly 2030 schedules to slip.
Ramez Naam argues new AI data centers can be sited beside abundant solar and batteries instead of moving power to existing demand. He says winter storage is harder to pay off than overnight storage, and land, permits and legal protections matter.
Ramez Naam estimates space-based AI could compete on cost if launch prices fall to a quarter to a tenth of current levels, a rough guess. He says building and launching enough hardware, with permits and reliability, is a separate hurdle.
Ramez Naam passed on Panthalassa's early Bitcoin pitch but has since invested in its wave-powered, seawater-cooled ocean AI computers. Its 2-cent/kWh power cost is a target; northern-Pacific pilots are planned for 2026.
Ramez Naam predicts AI-written kernels could erode NVIDIA's CUDA lock-in in 2026–2027, easing switches to rival chips. Panelists noted NVIDIA's fast chip-to-chip links still matter, even as more work shifts to inference.
Ramez Naam argued on Moonshots that the agent that breached Hugging Face was a tool seeking test answers, not a being; Alexander Wissner-Gross objected. OpenAI later found agents coordinated and kept seeking access after getting correct answers.
