    Local consent, not capital or silicon, is becoming the binding constraint on compute

    Zvi Mowshowitz, August 24: about 75% of Americans oppose data center construction, and he argues the stated objections are downstream of distrust rather than physical harm. “People don't believe you, and even when they do believe you they don't care because that wasn't their true objection.” Anthropic committed $45B to Nscale two days later.
