It feels like there is a shift in narrative. They use to complain that Chinese products being “cheap” because of inexpensive labor and non-existent slave labor. Now they are whining about the Yuan is being undervalued despite the fact the price of the Yuan has mostly been stable against the Euro/Dollar for the last decade. Saw people whining about this exact thing on Reddit. They are probably dreaming of Plaza Accord 2.0 where they can create a massive bubble and destroy China economy.

Seems to me they should just frame it as the Euro being over-valued which they can actually do something about.
But I guess that would require Europeans to admit they're backward and poor.

Anyone with a semblence of knowledge in computing should know that these so called installation of backdoors is complete non-sense. Computer chips are specifically designed to perform a strict set of functions. No GPU can magically connect to the internet in a hidden manner. Spying requires network connection and whatever data is being sent has to go through several protocols and layers before they are sent out.

Even windows firewall can detect unauthorized network access and block it, let alone multiple layers of firewalls and checks that high security computers will have.

This is just China using the excuse of a backdoor to stop Chip import from NVDIA. Just like US uses backdoor as an excuse to ban Chinese products.

But I do believe China should ban Nvdia completely. Only with a complete ban can Chinese AI companies be forced to develop the necessary software tools and libraries that are needed for efficient AI training and inference. They should be developing all the tools and software to make Huawei's answer to CUDA viable.

Clearly you need a bit more than just a semblance of knowledge to know backdoors are extremely easy to bake into chips and gain network access because of something called drivers.

Also Windows firewall? You expect Windows which doesn't even bother to pretend it's not recording your screen to protect against other backdoors, lol

And those are just simple backdoor, there are far more complex backdoors, like cyprtographic module RNG entropy attack, networking module attacks, PHY attacks, or just simply messing with your computation results.

It goes both ways: China can also backdoor basically everything with chips in it by replacing chips at production line, you can fit a networking IP die into just 1mm these days and you can build radiators into the chip using wire bonds which resonante with an enclosure. US might be projecting in saying China does that because there's no way to prove it, but China can very much do it and let's not pretend China does no spying.

So don't be naieve, obviously China's main interest is build domestic ecosystem and shut out Nvidia, but Nvidia backdoors are very much real

You are talking like Windows is the only OS and open source OS doesn't exist. Linux and derivatives do exist which are secure and completely open for inspection so that no software backdoor can exist. The OS acts as the central authority, controlling the CPU's privilege levels. Even drivers loaded from a chip must ask the OS for permission to access resources, like sending data packets. Its completely impossible for any backdoor piece of code to gain access to the network interface without OS permission.

Firewalls (both host and network-based) monitor all outbound traffic. A hardware backdoor trying to exfiltrate data would still need to use the Network Interface Card and transmit data, which network boundary firewalls and Intrusion Detection Systems are specifically designed to flag as unauthorized communication.

Finally, its too risky for a trillion dollar company to implement such a backdoor. The reputational damage will be too huge. We are talking the entire world and most of the top corps no longer trusting NVDIA products. Then there could be criminal charges and fines. NVDIA execs in China could be arrested for example. No company can justify doing these things. they would rather leak this to the outside world even if US govt forces them to do it.

There is tendency to come up with conspiracy theories against US where everything has a backdoor and CIA is all powerful entity that can spy on anything. When you think logically, you can see its all just BS.
