Overnight cutoff from EU tech would cripple US advanced semis. ASML's EUV machines are the only way to make leading-edge chips—US fabs like those for NVIDIA and Intel would stall on new nodes without them and critical parts. European talent loss would slow R&D pipelines. China gaining full EU access would rapidly boost its chip production and AI hardware, closing the gap fast. Short term: Severe AI compute shortages and training delays. Longer term: US could recover via CHIPS-scale domestic builds, Japanese/Korean/Taiwanese suppliers, and capital strength, but isolationism would make diversification slower and costlier. Major temporary setback.
