Once China has semiconductor manufacturing abilities comparable to Taiwan’s, one of the major deterrents to its invading Taiwan is removed. And outside of Taiwan it seems other countries are largely struggling to modernize and scale up their own semiconductor manufacturing, notably including the USA. China might see it as quite attractive to invade Taiwan and wipe out the West’s technology base, thereby ending up with the world’s most advanced manufacturing in China. Other countries would either have to suffer without computers or buy Chinese chips, and China would have de facto control of computing around the world, at least for a while.
