You keep singing the praise to US dominance in semiconductor when in reality US leadership in semiconductor is declining. As of today only 12% of all US chips demand is manufactured in US . The never ending delay of Intel 10 nm chip show that US is NOT in the lead anymore
The embargo and bullying on semiconductor technology to China does not show a self confidence of a domineering and successful technical giant Instead it show declining country

The truth is other than anything you said US leadership is semiconductor is the result of direct result of government effort to build small computer for Apollo program back in the 60's where they need small and compact computer to guide the space craft . And the huge effort in WWII to build radar and electronic warfare center on Stanford university in California . So many of the early pioneer in semiconductor naturally emanate from SFO bay area. Hewlet packard, Fairchild semiconductor the grand dady of all the semiconductor companies, personal computer pioneer Altair,Apple Steve job, Xerox parc reasearch, Berkeley etc all are in SFO bay area.
Not counting billion of dollar in government grant and research mostly weapon related to those Universities and companies in Bay area. The missile and rocket industries center on Lockheed facility in bay area

Yes government subsidy play an important role in shepherding a new technology. China was behind because she was a poor countries and was late in the game. People forget that China was backward and isolated until 1970's and University didn't reopen its door until early in 1980's. Yes good university is important that is why China expand the the university education maybe 100 fold since 1980
And China didn't have high tech industry until late 1990 after all Huawei was founded only in 1987. So all those talk of China cannot invent and government subsidy is useless is BS

well some are true, but the fact is US was able to push TSMC/ARM stop working with Huawei, seem like TSMC still using some US tech. As long this is true, Chinese company can't rely TSMC/ASML etc etc for their chips.

My understanding of the American bans against Huawei and what Ren Zhengfei is going to do moving forward, is that Huawei will buy stuff from MediaTek who is "fabless" but they will contract that chip manufacturing out to TSMC who will be using ASML top of the line machines to fill that order to supply MediaTek who would then supply Huawei.

Why are the Americans doing this?

There probably are two answers. One is to cripple Huawei, which is the public answer most of the time. Two is a more realistic, answer which is to slow Hauwei down in any way shape or form to delay they more running away with the 5G race.

How that is going depends on who is doing the talking.

Does Ren Zhengfei seem nervous? His daughter is in a Canadian jail conditions!

:oops:

Since Apple is going Arm, if they can figure out how to do x86 emulation well then China has a chance with its own Arm OS.

They won't need to. They will instead compile code into some p-code, which is dynamically complied at run time.

That is how Android does it. You can download an Android app straight from the Google Play store into an X86 powered Chromebook, whether its Intel or AMD powered, and run it. The app will run as long as the developer doesn't add any native (ARM) code extensions, a practice that has been discouraged for some time.

The ARM based Windows (Surface and similar tablets) also does this.

Statically compiled, distribution of apps in object executable code, is a thing of the past.

You write code, compile into p-code, and p-code is run by dynamic compilation completely transparent in X86, ARM or RISC-V.

But doesn't that mean more powerful softwares / applications can't be made (if using p-codes ? ). Games / Computer aided designing etc...

Huawei reportedly launches 'Tashan Project' to build 45 nm chip production line this year-cnTechPost'Tashan Project' to build 45 nm chip production line this year-cnTechPost

Huawei has launched the "Tashan Project" to make its foray into semiconductor manufacturing and is ready to build a chip production line without US technology, according to latest information posted on Weibo.

As a result of the US sanctions, TSMC cannot OEM Huawei chips, forcing the company to start the internal "Tashan Project", Weibo blogger @鹏鹏君驾到 said in a post.

Huawei has begun to work with related companies, ready to build a y 45nm chip production line completely without US technology, which is expected to be completed within the year, the blogger said.
At the same time, Huawei is also exploring cooperation with other companies to build a 28-nm chip production line of its own technology, the blogger said.
At an event last week, Huawei Consumer Business CEO Richard Yu said Huawei will be rooted in all aspects in the semiconductor field to break through basic research and precision manufacturing in physics and materials science.



In terminal devices, Huawei is investing heavily in materials and core technologies to achieve a close linkage between new materials and new processes, breaking through bottlenecks that constrain innovation.

Well, at least China has some kind of a plan to handle this future crisis in regards to the future and keeping people focused on a long term goal, while the USA and other western countries are too busy arguing and not doing any planning while people are losing jobs by the millions.

Hope in 2-3 years they can jump to 14nm or even 10nm with SMIC help.

Intel is still using 14nm and they're still comparable to AMD's 7nm.

If China can achieve today's intel 14nm performance in 2-3 years, then it should be able to stay independent while acquiring state of the art from TSMC.

This huawei is remedial in nature i thought they anticipate US sanction from beginning. I guess i am wrong then.
