“IMHO, diffusion models are as big a breakthrough as transformer models. It's a rare development when an architecture requires fewer compute resources than previous proposals.” https://threadreaderapp.com/thread/1560977033198555136.html

What It's Actually Like To Visit Factories In China As An Entrepreneur https://www.marshallhaas.com/post/what-its-actually-like-to-visit-factories-in-china-as-an-entrepreneur
China is now a major science & tech superpower, with huge consequences for political, economic & military power...
Most observers dramatically UNDERESTIMATE how good the best Chinese universities have become, especially in STEM education.

P.S. China has 28 times as many people who have an IQ above 160 as the United States despite only having 4 times the population. This means that China could launch 28 Manhattan projects at the same time.
If you want to gauge China's potential, look at Singapore. Singapore is essentially a 278 times smaller version of mainland China but with a significant headstart. A Singapore with 1.4 billion people might already have been the world power by now.
But this actually underestimates China's potential. The larger a country is, the easier it becomes to conduct large-scale scientific and technological projects. For example, a country like Iceland could never launch its own Manhattan Project, which employed more than 130,000 people.
