William David(@WDChokepoint):Kimi K3’s weights are live - 2.8 trillion parameters, only about 50 billion active per token. That efficiency is real. But the other 2.75 trillion still have to sit somewhere the moment someone self-hosts it. Sparse compute doesn’t mean sparse memory.

Physical reality constrains digital ambition. That gap is the investment thesis. Critical minerals. Semiconductors. Energy. The constraint always moves upstream
