There is currently sufficient incentive=
for the leading research labs to raise money and continue investing in new=
foundation models, even as competition drives API prices down relentlessly=
. Getting to a future where the US has a strong AI industry running on US-m= ade chips will take significant interventions in the market to undo the ove= rwhelming incentives for US companies to simply rely on TSMC. Such a shift = will take time, which is why making Taiwan indispensable to China's technol= ogy industry is the price that needs to be paid in the meantime.
