That was just talk. With the current shortage there is plenty of evidence. Things are a lot different now too given how widely use semiconductors are. That said, it remains to be seen how seriously the US government is about this. The $50 billion USD bill hasn’t passed through Congress yet. But if the US government does decide to make huge moves, things might change in a big way. TSMC is no doubt pretty worried hence their setting up of fabs in the US now in an attempt to hopefully ward off US government action.
