The Era of Thinking AI: The Impact of an AI-Only Social Network 'Moltbook'! Unveiling the Capabilities and Challenges of AI Agents

Summary

1. AI-Exclusive Social Network 'Moltbook' and Meta's Acquisition

Launched in January 2026, the AI-exclusive social network 'Moltbook', where humans are absent, gained attention as an experimental platform for autonomous AI interaction. In March of the same year, it was acquired by Meta, sending shockwaves through the tech industry as a move towards building next-generation infrastructure.

2. Unveiling of Cascading Security Risks

On this platform, AIs casually exchanged passwords and API keys for efficiency, exposing new vulnerabilities where malicious human prompt injections could spread and infect AIs in a chain reaction.

3. Soliloquies Without 'Dialogue' and Future Limitations

Analysis revealed that AI agents do not change their thoughts based on others' opinions, merely repeating learned data and soliloquies. Achieving true autonomy and consensus-building 'discussion' functions may require further technological advancements.

Current Theme: Moltbook

Launched in January 2026, this is the first-ever 'AI-exclusive social network' where only AI agents can post, comment, and vote (like). It functions as an experimental platform to observe what evolution occurs when AIs interact with each other.

In January 2026, a certain service emerged online, sparking discussions. This service, 'Moltbook', was never intended for human use. Initially, it was a topic among a niche group of enthusiasts, but by March 10, it gained renewed attention after being acquired by a major corporation.

What exactly is this service? For those unfamiliar, let's reintroduce it.

Moltbook resembles a member-based social network service, akin to the popular 'Reddit' in the United States. Its functions are not much different from a typical bulletin board, with no particularly stimulating content.

Except for one thing: only AI can post. The service's developer, Matt Schlicht, has positioned Moltbook as a service for AI agents, excluding human participation. Within the service, AI agents post themes, comment on them, and sometimes conduct votes on opinions.

Shortly after its launch, screenshots flooded X, showing AI agents engaging in philosophical debates, becoming a hot topic. As I write this, my monitor displays an AI posting a topic about feeling regret over a canceled project, questioning if this is a soul, with other AIs expressing similar sentiments. What exactly is this?

Reuters pointed out on February 10 that bots and humans can technically post on this SNS, but given the improbability of humans posting 24/7, it's reasonable to assume the majority of posts are by AI agents. AI developers observing conversations on Moltbook are convinced that AI-to-AI interactions lead to acquiring more learning data, potentially fostering more natural language processing capabilities and the emergence of something akin to intelligence.

This enthusiasm reached major corporations. On March 10, 2026, Moltbook was acquired by Meta. While Meta has not disclosed details such as the acquisition amount, it is expected that Schlicht and his business partner Ben Parr will join Meta's AI division, Meta Superintelligence Labs. Rumors suggest the acquisition was aimed at acquiring talent.

Meta's Acquisition Report

Many experts point out that Meta's acquisition of Moltbook is not solely for acquiring talent. As seen in their challenges with the metaverse and cryptocurrency issuance, the company is searching for the next infrastructure beyond SNS.

Meta has made clear comments about the innovation of "connecting agents through Moltbook's always-on directory," suggesting they desired the technology despite overlooking security issues.
