Lessons from Investment Gurus

The Most Important Thing

 Successful investing requires thoughtful attention to many separate aspects, all at the same time. 
Omit any one and the result is likely to be less than satisfactory.

The idea of the most important things—each is a brick in a solid wall, and none is dispensable. 

pretty insane.  i remember people were saying going below 5 would be impossible at industrial scale.  25% less power for 10-15% more performance in next year's iphones, probably desktop chips after that i'd guess

The Trump administration has revoked Taiwan Semiconductor Manufacturing Company’s authorization to ship chipmaking tools to China without a license, the chipmaker said on Tuesday.

This decision, part of Washington’s broader strategy to limit China’s access to U.S. technology, comes despite Trump’s recent actions to loosen some export control measures introduced by the Biden administration. Last week, the Trump administration revoked the waivers for South Korean companies Samsung Electronics and SK Hynix to ship U.S. chipmaking equipment to their China-based chip plants.

TSMC has a facility in Nanjing, China, where it produces chips for consumer electronics and industrial applications, and another plant in Shanghai that uses older technology not regulated by U.S. export controls. The company’s most advanced products, such as Nvidia’s artificial intelligence chips, are made in Taiwan and the U.S.

While the revocation does not completely ban TSMC from exporting U.S. chipmaking tools to China, the company will have to obtain approval from the Commerce Department to do so. The Taiwanese chipmaker said it is currently evaluating the situation and engaging with U.S. officials to ensure the facility in Nanjing can continue to operate without disruption.

Washington has revoked TSMC's fast-track status for U.S. chip manufacturing equipment exports to its main plant in China - a move that comes days after revocations of the same privilege for South Korean chipmakers.
