They have successfully captured the state and now span administrations.
Career politicians probably.
It only mean one thing, there is a LOCAL REPLACEMENT available.
This is nothing new. Has been happening for a while already.
Lenovo has some computer designs explicitly for the Chinese government market for example.
Some of them use Zhaoxin CPUs and Kylin Linux I think.
I still think Zhaoxin are being fools for using TSMC as a supplier though.

China's first large flagship telescope, slated , is expected to provide humankind with fresh knowledge about distant galaxies, mysterious dark matter and dark energy, and the past and future evolutions of the universe.
The Chinese Survey Space Telescope, also known as the , or Xuntian (meaning "survey to heavens" in English) Space telescope, is a space-based optical observatory for astronomers to carry out sky surveys, capturing a general map or images of the sky.
Wide-field telescope
The CSST is a bus-sized facility with a length equal to that of a three-storied building. It has an aperture of two meters, a bit smaller than the Hubble Space Telescope, but its field of view is 350 times larger than Hubble in area, said Liu Jifeng, deputy director of National Astronomical Observatories Of China (NAOC).
"The field of view is the area of the sky a telescope can see at one time," said Li Ran, project scientist of the CSST Scientific Data Reduction System. Hubble's field of view is approximately 1 percent of the size of a fingernail at an arm's length, thereby the telescope, in its thirties, observed only a tiny fraction of the sky, Li added.
The CSST, under construction, has a three-mirror anastigmat design that helps it achieve superior image quality within a large field of view, according to the researchers.
Also, it is a Cook-type off-axis telescope without obstruction that can, in principle, achieve better precisions in photometry, position and shape measurements when properly sampled.
"It has an advantage for survey observations since it can scan a large part of the universe fairly quickly," said Zhan Hu, project scientist of the CSST Optical Facility.
The CSST will be installed with five instruments including a Survey Camera. The main focal plane of the camera is equipped with 30 81-megapixel detectors that will take images and spectra of roughly 17,500 square degrees of the median-to-high galactic latitude and median-to-high ecliptic latitude sky in multiple bands, according to the researchers.
Another four instruments mounted on the CSST are designed to observe individual objects or small fields, like mapping star-forming regions of the Milky Way, obtaining instantaneous color of fast varying objects such as comets and spinning asteroids, studying the co-evolution of supermassive black holes and galaxies and star formation in the nearby part of the universe, and direct imaging of exoplanets in the visible.
CSST is likely to be the largest space telescope for astronomy in the near-ultraviolet and visible in the decade before 2035, Zhan said.
Li used the analogy of photographing a sheep flock to explain CSST's capabilities. "Hubble may see a sheep but the CSST sees thousands, all at the same resolution," he said.

Flying with the space station
The telescope, during its normal observations, will fly independently in the same orbit as China's space station but will maintain a large distance apart. China is scheduled to .
Zhan said the telescope was designed, in its initial plan, to be mounted on the space station, but there would be disadvantages such as vibration, potential contamination, stray light and line-of-sight obstruction from the space station. Later, a bold design was adopted – putting the telescope in the orbit of the space station but keeping them far away from each other during normal operations and docking it with the space station when necessary.
The CSST can dock with the space station for refueling and servicing as scheduled or as needed, making its maintenance more affordable than Hubble.
The U.S. space agency NASA launched space shuttles in five servicing missions from 1993 to 2009 to perform repairs, replace parts and install new instruments for Hubble.
The CSST is expected to start scientific operations in 2024 and has a nominal mission lifetime of 10 years, which could be extended in principle.
Unraveling cosmic mysteries
The CSST will take pictures of 40 percent of the sky and transmit massive data back to the Earth that scientists all over the world can study, Li said, adding that its main objective is to address the most basic problems about the universe.
It will observe well over one billion galaxies and measure their positions, shapes and brightness which may help explain how those galaxies evolve.
"We have known that our universe is expanding with an acceleration and we can calculate its current expansion rate, but it's still unknown what causes the acceleration," said Li. "CSST observations may offer answers and unveil new physics."
The telescope will also be able to help determine the upper limit of neutrino mass and shed light on the mysterious dark matter and dark energy. They're believed to account for the majority of mass-energy content of the universe.
The versatile telescope can undertake many more intriguing studies such as drawing a galactic dust map of the Milky Way, observing how super-massive blackholes are gobbling up surrounding materials, exploring exoplanets and discovering new peculiar celestial bodies.
"The orbital period of Uranus is more than 80 years. Hubble has made [observations] for many years. The CSST could continue the work to examine how Uranus moves in one complete period," Li said.
"The telescope can bring China's research in optical astronomy to the forefront of the world and help cultivate world-class Chinese scientists," Li added. "It can also take breathtaking visible pictures, allowing the public to directly feel and understand the universe."
Artificial intelligence and the internet of things will see wider industrial applications in China as more local companies are speeding up digital transformation and deploying innovative technologies to improve operational efficiency and reduce costs, experts said.
The comments came as 60 percent of enterprises in China are expected to embrace digitalization by 2025, according to a five-year plan unveiled by the Cyberspace Administration of China, the nation's top internet watchdog.
Zhao Kang, who is in charge of enterprise-oriented business at Megvii, a Chinese AI pioneer, said digital transformation is no longer a choice but a must for local enterprises. The COVID-19 pandemic has also prompted all walks of life to accelerate the pace of digital transformation. Meanwhile, digitalization is also a golden opportunity for Chinese companies to become more competitive on the world stage.
According to Zhao, China has strong policy support to promote the development of AI, which has transitioned from a budding phase to a stage of growth and maturity, with the technology generating more commercial value for a wide range of sectors.
In the era of intelligent IoT, improving the efficiency of a single device or equipment is no longer enough. What is in dire need is an overall improvement in multiple dimensions. That is what the combination of AI and IoT, or AIoT, can deliver, by enabling a two-way interconnection of devices' capabilities to perceive and execute tasks, making it possible to analyze all data autonomously, Zhao said.
Seeing AIoT as a golden opportunity for the next decade, Megvii has unveiled a string of products and solutions to empower enterprises to access greater computing power at more affordable prices, and to facilitate industrial applications of AI and IoT.
AIoT must be combined with specific scenarios and industries, with customers and with partners to truly unlock its value and to promote digitalization, according to Megvii.
Market research company International Data Corp predicts that direct investment in digital transformation worldwide will surpass $6.8 trillion between 2020 and 2023.
Wu Lianfeng, vice-president and chief research analyst of IDC China, said Chinese enterprises are facing new challenges and more than 80 percent of enterprises are poor in digital resiliency.
Digital resiliency is the ability of an organization to rapidly adapt to business disruptions, leverage digital capabilities to maintain continuous business operations and quickly adjust to take advantage of changed conditions.
Li Wei, deputy head of cloud computing and big data research at the China Academy of Information and Communications Technology, a Beijing-based government think tank, said enterprises should speed up the pace of digital transformation, concentrate on consumers' requirements, integrate online and offline channels, as well as promote the transformation and upgrade of traditional industries.
