Meta's Muse agent just pulled them back into AI Tier 1 by nailing task completion with a hybrid human-AI loop.

The killer detail: phone calls are where AI agents usually die—merchants hear "AI" and hang up instantly, breaking the entire flow. Meta's fix? Zero purity obsession. They built a real human call center as fallback, pushing fulfillment to 95-98%. Ship first, collect training data while running, then iterate. Users want results, not philosophical debates about "pure AI."

Distribution is even more brutal: Meta flooded their own traffic ecosystem so hard that rural US grandmas now know Muse—same scale as Douyin's Doubao push during Chinese New Year.

The formula: massive traffic pool × ground-level user insight × zero ideological baggage about human-in-the-loop. This playbook benefits $META and mirrors what Tencent/ByteDance are doing in China—pragmatic AI that actually closes loops in messy real-world scenarios.
