The Download: squeezing more metal out of aging mines, and AI’s truth crisis

Microbes could help extract metals needed for clean technology as aging mines struggle to meet demand. The increasing need for nickel, copper, and rare earth elements for data centers, electric cars, and renewable energy projects is challenging due to depleted resources. Meanwhile, concerns about AI's truth crisis are rising, with content manipulation eroding societal trust. Hyperscale AI data centers are emerging to support large language models, but at a significant cost. Additionally, SpaceX's acquisition of xAI and delays in NASA's Artemis II launch are notable tech developments.
