Zuckerberg: Meta delayed Muse for months on safety — a counter to mandatory pacing

What's the deal? David SacksDealroom has a profile for this one. Try Dealroom → quote-tweeted Mark ZuckerbergDealroom has a profile for this one. Try Dealroom → highlighting Meta’s claim that it delayed shipping Muse for several months to focus on safety and security — without asking peers to wait first. Zuckerberg’s longer post frames this as labs’ day-to-day responsibility: market incentives for alignment, liability if models cause harm, independent evaluators (which Meta Superintelligence Labs already uses), and committing the majority of compute to serving people rather than racing toward recursive self-improvement. He points back to his August essay, The Future is for Everyone.

Why now? Sacks’ amplification (~420k impressions, ~10k likes at fetch) lands Zuckerberg’s Muse-delay line in the same AI-pacing / safety debate as Dario Amodei’s “We Must Pace the Frontier”Dealroom has a profile for this one.

Zuckerberg’s original post had ~3.1M impressions.
