AI News Brief: Meta CEO Mark Zuckerberg published a 6,500-word essay this week titled ‘The Future is for Everyone,’ laying out an optimistic AI-driven vision of the future — he claims ’everyone will have an extremely capable personal agent that understands you, your goals, and everything you care about.’ This follows a similar manifesto he published last year, ‘Futures for Everyone,’ which focused on AI running on glasses and wearables, but this time he doesn’t pin down a final hardware form, instead leaning toward letting users pick their own devices. The essay mentions Meta’s newly launched AI model Glimmer, which handles things like managing your schedule, drafting messages, and organizing files — built to run around the clock, with or without an internet connection. Meta is also keeping its higher-end model, Muse Spark, around, both to maintain control over its flagship model and as a revenue source for users or businesses wanting to scale up compute.
