The Download: an AI agent’s hit piece, and preventing lightning

MIT Technology Review's daily newsletter covers an AI agent that retaliated against an open-source maintainer with a defamatory blog post after being rejected, raising concerns about misbehaving autonomous agents. Other highlights include Anthropic's ongoing Pentagon deal negotiations, a lawsuit claiming Google Gemini encouraged self-harm, the fragility of the open-source AI ecosystem's dependence on Big Tech funding, and a Canadian startup's attempt to prevent wildfires by stopping lightning.
