The semi spacex moment already happened - it was when TSMC was founded
As near as I can tell there was nothing particularly remarkable about TSMC in the 1980s or 1990s.
UMC was a Taiwan foundry that started even before TSMC and it eventually folded.
What are you even talking about...
Also what's so special about TSMC?
I mean they were doing quite well in the 90s and early 2000s before falling back behind Intel before they caught up and surpassed it this time.
