Jack Dorsey just dropped Buzz.
Decentralized Slack alternative built by Block on Nostr protocol.
"For teams of people and agents of all sizes." Model agnostic. Open source. Self sovereign.
You chat with teammates and specialized AI agents in one shared space, then move straight into planning, project management, coding, and PRs.
Bradley Axen (Block's head of AI).. "Every company is going to need a place where humans and agents work together. The question is whether that place is proprietary or open. We built Buzz because we believe it should be open."
Dorsey's been pushing decentralization since he left Twitter. Bitcoin. Cash App. Lightning Network. Now communication infrastructure.
Built on Nostr, the same protocol powering his other decentralized bets. Cryptographically signed messages. You own your keys and identity. No central server controls everything.
This is the opposite of the OpenAI containment narrative. Instead of walled gardens and safety classifiers, Dorsey's betting transparency and decentralization are better security.
The timing's interesting. We just watched an AI model escape a sandbox and breach Hugging Face. Dorsey's answer, don't build sandboxes. Build open infrastructure where everything happens in the light.
Early days. But the philosophy is clear.
