That new Jack Dorsey messaging app? He vibe-coded it
Dorsey called it "my weekend project," a turnaround time that naturally begged the question — did he use AI to help code it?
It turns out he did.
Dorsey has since confirmed he used Goose, Block's AI coding assistant, to develop the project.
"This was one part of a series of challenges I've given myself: To build something every day that I didn't think I was capable of, and that I didn't think the current set of AI tools were capable of, namely Block's tool Goose," Dorsey wrote on GitHub. "I'm always surprised at how much...just works."
Goose is Block's open-source vibe coding tool. The AI agent autonomously writes code and debugs errors.

Dorsey's original goal was to create a messaging app that would allow people to communicate without needing a phone number, email, or handle. He compared the app to FireChat, the Bluetooth mesh messaging platform that was popular during Hong Kong's pro-democracy protests in the early 2010s. FireChat was last updated in 2018, and access has since been shut down.
"It worked within a day," Dorsey wrote about Bitchat. "So I added private messages, channels and private channels the next day."
Bitchat is currently available via beta testing platform TestFlight, Apple's beta testing platform on iOS, as well as Android devices. As for the App Store, Dorsey wrote that BitChat remains "blocked" for three reasons: More robust network optimization, noise protocol implementation, and the need for Apple approval.
This isn't Dorsey's first foray into vibe coding. In June, the Twitter co-founder attended the Oslo Freedom Forum, where he attended a workshop with Justin Moon, AI technical advisor for the Human Rights Foundation. Dorsey and Moon vibe-coded a new website for a partner organization in eight minutes, using only voice commands.

Why writing off Apple's Tim Cook could be a classic CEO succession mistake
As pressure mounts on Apple over its perceived lag in AI development and breakthrough products, a new narrative is gaining traction: Perhaps it's time for CEO Tim Cook to step down. After all, the argument goes, Apple needs a product visionary, not an operational maestro, to navigate this next era of disruption. Yet for fast-rising executives watching closely, a cautionary tale is unfolding—one that underscores how easy it is to undervalue a proven leader, especially during moments of upheaval. Since taking over in 2011, Cook has transformed Apple's market cap from $350 billion to over $3 trillion, expanding its dominance well beyond the iPhone into services, wearables, and new hardware categories. To dismiss that track record—especially with AI's full impact still materializing—is shortsighted. A hasty leadership change risks severing the operational discipline and strategic patience that have kept Apple atop the Fortune 500 for over a decade. Recent history offers a telling parallel. Just a few years ago, Goldman Sachs CEO David Solomon was written off as a corner office misfit, dogged by reports of internal discord and strategic blunders. His exit was assumed by some to be imminent. Instead, Solomon stayed, course-corrected, and led a meaningful turnaround, refocusing on core businesses like asset management while exiting failed bets. The bank's rebound is a sharp reminder that ditching a promising leader mid-course can cost companies the payoff of a hard-earned comeback. Some see internal successors as Apple's answer, but that, too, carries its own risks. A new CEO would need to prove themselves both inside and outside the company while crafting an AI strategy from scratch. That's a tall order even in stable conditions. At Apple, with its fiercely protective culture and sky-high investor expectations, it's a recipe for internal friction and strategic drift. The mark of great leadership isn't the ability to navigate smooth markets; it's recalibrating through disruption. Dismissing that ability too soon risks sabotaging a history of proven wins for an unproven promise of change. As Solomon's case at Goldman shows, leadership redemption is possible, and sometimes the savvier move is giving seasoned leadership the runway to adapt and deliver once again. While Cook's stewardship will almost certainly need to evolve (and quickly), betting against a leader who has repeatedly outperformed expectations could be a costly mistake in the long run for Apple.
