Princeton 3D mesh harnesses living neurons

Interesting science, but still far from a practical compute platform. The real breakthrough is a stable 3D interface for steering living neural networks with enough precision to study how they learn.

• –Six-month stability is the key technical milestone; most prior brain-cell computing setups were too fragile or too externally probed
• –The pattern-recognition result is proof of concept, not a silicon challenger, even if the energy-efficiency framing is compelling
• –Near-term value is likely in neuroscience, drug testing, and brain-machine interface research rather than mainstream AI workloads
• –If scaling improves, this could become a niche neuromorphic research platform instead of a general-purpose replacement for digital compute
