Are you legitimately saying that we should treat Taiwan as the same as China just because its citizens are the same race? Jesus fucking christ, dude. Take a deep breath, look in the mirror, and reconsider that racist ass position.

Straight up Tankie shit, the rest.

Do you know the history behind the creation of Taiwan?

Yes, the creation of Taiwan... in 1624. Or, if you want to talk about the China's history of Taiwan, then it's 1945.

In either case, way too fucking far back to have any sort of diplomatic weight in a conversation, except as an excuse for racism.

The issue arises when you look at it from a geopolitics point of view. The US (aka the West) loosing manufacturing and design dominance in the semiconductor space means that there is less bargaining power to force others to do what the US wants. In the case of China, US export embargos for cutting edge semiconductor technology was meant to cripple China's technological progress, especially in the semiconductor design/production and AI model space. (Think of whatever shenanigans US companies have been doing with AI models, and what China has already demonstrated on Western hardware.)

Semiconductors are integral to modern weapon systems. If you've been keeping up with the news, you'll remember that even Russian missiles have been found to contain western-made electronics. AKA Russia has been buying US technology and adding it into their own weapon systems, rather than designing, producing and using their own. That makes Russia reliant on having a stable source of US components, be it imported legally or in spite of sanctions. The same goes for China. The fear is that China will eventually be able to manufacture weapon electronics comparable to US designs. Stealing the designs from US sources isn't particularly difficult, its always been the manufacture of said components that caused issues for China. Seemingly, that gap has been closing.

In short it's basically the issue of the West having made China the factory of the world, them having learned/being able to steal designs, and them now having the ability to produce almost anything. That makes them a strategic threat to US interests.

Anything that makes someone less reliant on you is a net negative if you wish to remain 'in charge'.

The less economic and tech dependencies China has on the West, the more free they are to act on their own accord.

The US is concerned about Taiwan-- they wrote a blank cheque of support because it was a DeMoCrAcY back when China was a far weaker economy and military, and it will now be very difficult and expensive to stop reunification. Using TSMC as a shield is no doubt part of policy-- "invade and we blow the tech world back to 2010" is a viable threat until other countries get 7/5/3nm.

But their fear is more general; they are losing their economic and geopolitical dominance, and one of their big bulwarks-- advanced tech-- is giving way. They're trying to hype up the fear and concern. Expect a lot more sabre rattling by the West.

The answer rather depends on where you live.

Yeah I have literally zero more information lol I'm in the US and feel like I should be concerned because "China" but I'd love a valid reason beyond "they're now capable of sustaining they're own technology".
