Even with this example, the Tianhe uses an exhorbitant amount of power, is not globally competitive and is no longer the world's fastest supercomputer anyway
You are confused. That is America's Titan computer that is massive and guzzles energy. Chinese computers are always innovative and while not as green as Japans, they always take innovative approaches rather than just sizing up and drinking power like Titan.
Given that the Chinese engine project is decades-old and still doesn't have an effective product (and meanwhile foreign competitor aviation systems have a complete supply chain to fuel sales & further R&D), I think we know the answer.
The answer is that China has really only recently made modern efforts in the civilian sector. A decade ago, J-10's were all powered by Russian engines and now, every aircraft in the PLAAF has an operational Chinese engine version. That was the Chinese dream 10 years ago; now China's already moving on to better things.
A more pertinent example would be how the US has embargoed avionics and engine parts to China for decades and yet...
And yet China still developed them for its fighter jets, which took priority and are, in parts, more difficult than passenger jets.
No, a computer doing decades-old computations isn't impressive. It's as impressive as a company making paper or gunpowder
Except China's exascale computers are faster than America's; they're just now announced instead of being openly shown at the TOP500. Probably China has become privy to the risks of letter Westerners probe its best computers.
China isn't doing a good job developing its aviation industry anyway even after decades of garguatan efforts.
Decades have been used for military jets and there is no denying the growth and development of the PLAAF. Efforts towards a civilian jet by a modern China have only just begun.
Why should anyone be impressed with a machine that solves decades-old problems inefficiently?
Cus it's better than what they've got.
It's why techology denial works
To spur innovation in China.
China either being helplessly dependent on the West or a technical laggard are both optimal outcomes.
Optimal for the US, but unattainable, and America's panic is telling.
Right: in the supercomputer case, China can either have extremely large, power-guzzling CPUs or be helplessly dependent on Intel and Nvidia.
You have Chinese computers confused with America's Titan. American banned these chips to China and China made them itself. Perfect case of tech denial backfiring.
Re: ZTE and Huawei, China can either have them depend on the West or no 5G
Huawei makes 5G all over China under all US sanctions. And no 5G isn't an option for the US; it's the only reality as American 5G is just 4G rebranded.
. It's a win for the United States, any day, all day.
If it wins any harder, it might be able to make out China's license plate number as it gets zoomed past in every field.
Sit and wait and wait. The SMEE ArFi, MA700 and C919 are all hopelessly delayed
We can wait; don't worry. China has waited decades and every one of its world-leading tech fields was at one time, "hopelessly delayed" according to pundits. But China always has hope and always pulls through; the word "hopeless" is Westerners trying to project their situation onto China.
