Agentic AI and the next intelligence explosion

6 silverpiranha 2026-03-30 21:43:20 UTC arxiv.org Prefix Share 0

The "AI singularity" is often miscast as a monolithic, godlike mind. Evolution suggests a different path: intelligence is fundamentally plural, social, and relational. Recent advances in agentic AI reveal that frontier reasoning models, such as DeepSeek-R1, do not improve simply by "thinking longer".
