Chinese law requires companies to make provisions for representing the interests of the CCP within companies of significant size. This isn’t a conspiracy, it’s routine business law. There is no need for the CCP to conspire to control businesses. They have ultimate control of business law. The idea that companies and governments are independent things is a pretty capitalist perspective. There’s a wide range of other p…

It works the same way in capitalist countries - except it’s enforced with money and patriotism instead of democratically introduced, officially existing rules.

They’re “the same” only in a reductionist sort of way that isn’t very conducive to productive conversation.

Varying economic and legal systems are different in the specifics about how they work, even if self interested individuals exist everywhere.

In case HN readers doesn’t know, ML based MD scales O(N) and traditional DFT based simulation O(N^3) where N is number of atoms. From first hand experience: what used take weeks with traditional DFT MD on CPUs are only taking few minutes with GPUs right now if you have trained a good ML potential. They achieved near DFT accuracy.

This type of complexity argument is also used in graphics rendering as far as I am aware. In graphics, it just has to look ok. Is there any concern for bounded error in MD?

Well in MD you always have to compare to experimental measurements from a macroscopic level.

And you have to repeat DFT results as far as you can do DFT on it.

Modeling user brain chemistry? Ominous.

self-aware General AI who's existence is entirely made of simulated eons of watching tiktoks

All much too complicated, they are just interested in someone coming up with more "what happens if you put mentos into coke"-type reactions for their content creator's inspiration..

Yeah, this isn't really that different than quant hedge funds hiring theoretical physics PhDs. It's not like you're actually going to be doing Yang Mills field equations to trade some stocks. They just need a guy to run some linear regressions, and can afford to find someone really really overqualified so they don't screw up.

Not sure if these people are overqualified as much as the fact that people who check the box on paper are generally unqualified. Generally good people can only really do math up to a few years below the highest level that they learned in school. If you actually need someone to do basic linear algebra you probably want somehow who took classes that went well beyond the freshman/sophomore level that everyone has.

No, it's really about material science and biology, just read further in the ad: Responsibilities • Follow the latest progress in computational science such as material and biology. • Solve real-world problems in material and biology, with computational approaches such as molecular dynamics, quantum chemistry, and machine learning. • Optimize and speed up classical molecular dynamics and quantum chemistry algorithms…

That will be cool if their really looking to expand into something useful like biochemistry r&d, similar to Google with deepmind.

TikTok brain implant?

Let’s hope so. Not enough of this in the world: “We choose to do these things not because they are easy but because they are hard” But I’d be happy with a little Bell Labs at a few more companies

They would have to spend a LOT more to go bell labs. Until now they spend way too little to achieve anything. And for companies like Google have real managers for those groups instead of people only good at optimizing metrics.

Bell Labs is a good example of Icarus syndrome, I'd say they're doing that just fine.
