The 30,000th wake-up call for EU. Spoiler alert: it will still not wake up.
That ship has sailed for the EU. We just accepted that all the cool SW comes from the US and we just buy it from them instead of making our own. Who cares about SW jobs in the EU anyway?
But they won't be cost effective, might be around the same price as an Intel/AMD/ARM chip. Being new, the adoption would be slow as well.
Only way to change that would be for the EU to ban imported chips so that there's no way for the consumers but to buy local which amounts to trade war.
Therefore, I don't think so there are much (rational) choices as of now.
