Instagram head Adam Mosseri predicts artificial intelligence will fundamentally alter online content, making authenticity paramount. He suggests the era of highly polished, perfect images is ending, replaced by a preference for more 'raw' and unproduced content. Mosseri anticipates a shift where users will focus more on the creator and less on technically flawless visuals, as AI makes perfection easily reproducible. He also foresees a future where cryptographic signatures verify real content, rather than relying solely on AI detection.
