> 'opened the kimono' Kimonos are Japanese, not Chinese. EDIT: I understand that 'opened the kimono' is already a phrase but it seems like it was used because the article is about china.

This particular (and rather creepy) metaphor gets used by some business-side people and press in a general context, not just when talking about Japan. It's been around for decades.

Is the US slowly bowing out of the international tech scene? China is still going to get their processors from somewhere, the difference is if they don't get them from US companies then no money gets added to the US economy when they do buy their chips. This type of government interference doesn't hurt Chinese businesses at all, but could damage or destroy US-based businesses that may depend on foreign customers to s…

It is perhaps naive to assume that any given part can be had with identical properties and costs from American or non-American suppliers. Also, there are other considerations at hand, such as making life harder for foreign intelligence agencies.

From what I could decipher from the end of the article, it sounded like China has already migrated away from Intel's architecture and replaced it with a different architecture they could get their hands on more reliably—meaning even if the US were to reverse their decision about this denial list, the damage to Intel is already done. This may have killed the demand for Intel's products in China, even if they were free to sell them.

If you owned a Volkswagen car and required specialized parts which were were denied to you, and you upgraded to a different make of car like Volvo, what good would Wolkswagen spare parts serve to you? You're not going to switch back to VW just because the spare parts are available on the market again…you've moved on by that point.

As we say where I live: «L'avion c'est en vol!» (“The plane has taken off” ~= That Ship has sailed)

I really can't imagine this has any impact on any chinese intelligence agency whatsoever. Tianhe-2 is already the #1 supercomputer - what possible difference could a minor (it's not an order of magnituge faster, and software doesn't scale perfectly anyhow) upgrade make?

Earlier quoted context omitted.

I'm not willing to give the government the benefit of the doubt anymore. I can't recall any instance historically where they have turned out to have been right based on some secret information, even though they often intimate that they have some.

It happens quite a lot. The catch is that the whole thing end-to-end is secret, with the result being that you don't hear about it at all. All we really hear about on the outside is the screwups. The successes are silent.

This kind of ban was never going to be silent, so I don't think it's reasonable to a serious selection bias here.

It's naive to assume that America makes all the processors.

Intel and AMD have fabs all over Europe and the Middle East. Germany and Israel are known for their processor fabs.

Processor makers are multinationals, not national companies. Both AMD and Intel are bigger than the US.

If China stops buying from major multinational US companies, the entire Western tech industry will be hurt. No American jobs are lost when a German AMD fabricator has less demand.

China needs not to worry about this.

And by the way few people do math "heavy lifting" with x86 CPUs today, they would rather do it in a GPU

China has the fabs and the expertise (or at least it is getting there). It's a non issue.

"They have taken the best that the USA has developed (some of key Alpha, GPGPU and MIPS architects left US over the course of past four years, a lot of them due to non-renewed visas) and discarded due to corporate shenanigans, and the continued developing it much farther than anyone expected both on hardware and software side. "

I read jeffbush's comment as a broad one, rather than narrowly about trade restrictions. The government is often right based on secret information, but selection biases are strong.

Those Xeon chips are mainstream server chips, are they not? And this restriction seems to affect only a few Chinese entities. So what's to stop China from getting the same chips from Intel through another company? Is the U.S. just going to play whack-a-mole with them? Also, the reason given for this is so hilarious. China is using the supercomputers to "research nuclear explosions". China is doing WHAT?! Stop the pre…

> Also, the reason given for this is so hilarious. China is using the supercomputers to "research nuclear explosions". China is doing WHAT?! Stop the presses! China is going to have a nuke!

The ability to computationally model nuclear explosions is strategically important. This permits development of new nuclear weapons designs without violating the Comprehensive Test Ban treaty.

It's a figure of speech, not a cultural reference. It's a term used for pragmatic openness between companies. Avoiding secrets. I prefer using the term 'lay your cards on the table'. Less charged.

Wow, he was busted for exporting FPGAs that were rated for the wrong temperature range. I'm not saying it wasn't nefarious, but it is crazy that Automotive grade is completely legal at -40C - 125C and but go a little colder to milspec (-55C - 125C) and you are going to jail.
