Local open-source models on consumer accelerators (Apple M4 Max, Nvidia DGX Spark, RTX 4090) now deliver 88.7% of query quality with 3x better intelligence-per-watt and 18x better intelligence-per-joule versus two years ago. Perfect routing could shift 80-90% of inference demand from cloud to local devices, yielding 50-70% energy/compute/cost savings even with imperfect routers — fundamentally altering data center capex economics.

Local open-source models on consumer accelerators (Apple M4 Max, NVIDIA DGX Spark) now deliver 88.7% of frontier capability at radically lower energy/cost. Intelligence per watt improved 3x in 2 years; per joule 18x in 16 months. Perfect routing saves 80-90% energy/compute/dollar; imperfect routers still save 50-70%. This fundamentally rewrites inference capex economics and data center build-out assumptions.

AI coding agents remove implementation bottlenecks; the constraint becomes learning velocity. Young founders who tinker at the edge of model capabilities discover non-obvious startup ideas faster than whiteboard strategists.

Google's core search monopoly funds massive R&D but bureaucratic structure prevents execution; key inventors (Jeff Dean, Noam Shazeer, David Silver) leave to raise billions for GPU clusters because Google cannot allocate compute internally. Short-term stock positive (cost discipline), long-term innovation exit like IBM/Intel.

YC's investment thesis centers on founder qualities — taste as intentional product decisions driven by customer insights, and agency as the ability to will outcomes into existence — not on ideas, which routinely pivot.

Severe HBM/DRAM shortage blocks Apple N2 phone production and limits every Taiwanese AI product; CXMT's pricing power proves structural undersupply that favors memory makers over logic foundries.

Memory is the binding constraint across the supply chain — Apple has N2 chips ready but cannot get memory for phones; CXMT has full order books and pricing power; fastest path to revenue for Elon's Terafab would be memory production. All specs are open, making entry feasible.

Proposed US ban on Chinese data center components (transceivers, humanoid robots) targets areas where China leads (optics, 1.6T/16T transceivers). Entire supply chain sits in China; banning imports raises costs for Western hyperscalers without viable domestic alternatives. China evades letter of law via Vietnam/Thailand routing.
