Elon Musk's X is the AI community group chat

Elon Musk bought Twitter saying civilization needed a "common digital town square." Four years later, it's more like a live group chat for Silicon Valley's AI obsessives .

Why it matters: Two years ago, X was fighting off competition from a slew of new entrants.

Today, it remains relevant by becoming more niche.

The people making AI news are often debating it, explaining it and occasionally breaking it on X before the rest of the information ecosystem catches up.

State of play: New model releases, research papers, demos, hiring moves, high-profile executive exits and technical arguments ricochet through X in real time.

The latest viral example came Tuesday when Anthropic researcher Jacob Coxon announced his resignation on X, along with a thread explaining his safety concerns.

The post has over 100 million views.

Another Anthropic employee chimed in to say he thinks there's a >10% chance that AI could kill all humans in the next decade.

The combination sparked a ferocious news cycle about the dangers of scaling AI, and it was all kicked off by two employees posting on X.

Flashback: The AI community, particularly the researchers who define the technical progress happening within frontier AI labs, has long coalesced around ideas on X.

Back in 2025, AI researcher Andrej Karpathy coined the term " vibe coding " in an X post, helping name one of the defining trends of the AI enterprise adoption curve.

Even executives are now engaging more with the platform as a communications tool, with Nvidia CEO Jensen Huang launching his account in July alongside a post supporting open AI models.

Researchers from Chinese AI labs are breaking geographic boundaries to reach new audiences on X, per Wired , which is part of what helped catapult open models to their current popularity .

Zoom in: Huge investments in live video have made X a go-to platform for new live tech shows, such as "TBPN," " Stabledash ," " MTS Live " and others.
