Which brings us right back to my point. They aren’t wizards, they are simply benefiting from the enormous government investment into the extremely expensive chip manufacturing industry.
Their manufacturing efficiency is top tier, their government built facilities are top tier. However they weren’t first, they aren’t the only ones who can produce them and now that the US is interested in chip manufacturing again the new facilities will match TSMC in a few years.
What Taiwanese technology? Name some.
Intel is building fabs, TSMC is moving away from Taiwan due to the geopolitical risks.
