gizmodo.com Ellyn Lapointe 2026-02-24 20:52:26

On Sunday, June 29, Indonesia will break ground on a $6 billion electric vehicle (EV) battery plant on Halmahera, the largest of the Maluku islands. The facility will mine the island’s abundant nickel reserves and manufacture batteries on-site to reduce production costs in Indonesia, but a watchdog warns it could decimate an uncontacted tribe. The Hongana Manyawa—whose name means “people of the forest” in their language—are one of the last nomadic hunter-gatherer peoples in Indonesia, according

Graphic artists in China push back on AI and its averaging effect

Sendi Jia, a designer running her own studio between Beijing, China, and London, England, says she mainly uses AI generators like DALL-E to make fake photos for background panels or websites when her clients don’t have access to real ones. That’s helped clients with limited budgets, but it’s also exposed just how much of the creative process AI can replace. Recently, a potential client working in a university contacted Jia about creating the logo for a new project. Then, they changed their mind.
