Why AI Models Pay for Weights They Never Use
MoE architectures decouple compute from parameter count, but they impose massive networking overhead and latency penalties.
Why is Memorization a Software Defect in AI?
The boundary between a model that memorizes and a model that understands is not a gradual slope; it is a sudden, phase-shifting snap. True generalization often requires training far beyond the point of apparent failure.
Why is Vector Distance a Poor Proxy for Meaning?
As dimensions scale into the thousands, the fundamental laws of geometry warp. Proximity in a high-dimensional embedding space is often a statistical mirage, not a guarantee of semantic relevance.
Why is AI Training Throttled by the Chain Rule?
Backpropagation forces global synchronization on hardware that wants to be local. The memory-bandwidth tax of the backward pass is the primary ceiling on AI scaling.
