The human brain's extreme energy efficiency, estimated to be 10,000 times greater than current AI models, is attributed to its sparse and localized processing. While techniques like mixture-of-experts offer a path toward similar efficiency in AI by using specialized sub-networks, they may reduce the benefits of superposition. Superposition, a dense shared representational space, allows neural networks to compress multiple features into the same neurons, contributing to their power but hindering interpretability. The author posits that more segmented architectures could weaken superposition, potentially making AI models easier to inspect and govern, and seeks a balance between efficiency, power, and interpretability.
