The Chinese hackers can steal the HFSS the world's most effective R&D program.

"Yaoguang software has been available for free for the past few months. (Representational image)" (InterestingEngineering, China releases ‘world’s most powerful’ weapon design software, 15x faster than US)

Chinese developers released new software that fits the weapon research. That program is similar to U.S. software that U.S. developers used for simulating magnetic catapults and other kinds of military stuff. Chinese developers gave their software name "Yaoguang". The program is a Chinese copy of the HFSS the most effective material and electromagnetic simulation program in the world. 

Developers made The Yaoguan similar complex simulations as HFSS. But it's faster. 

That can mean that the Chinese use better supercomputers than Americans. Or they use something differently than HFSS users. 

Or the code in the program is tuned better. Those simulations require high-power computing. But Yaoguang makes those complex electromagnetic reflection simulations faster. The HFSS uses three hours for those simulations. The Yaoguang does it in 12 minutes.

And that makes this problematic. It's possible. That the Chinese hackers stole the HFSS source code. And then they can make changes to that software. That requires the necessary programming skills. Those changes can involve more advanced memory control. That makes it more powerful. 

"Yaoguang takes just 12 minutes to perform radiation simulation analysis on the multi-band antenna used in the new phased array radar while Ansys HFSS, a powerful electromagnetic industrial software in the United States, takes three hours to complete such tasks." (Interesting engineering, China releases ‘world’s most powerful’ weapon design software, 15x faster than US)

If the developers connect an HFSS-type development tool with a large language model. That makes it the most powerful tool in the development process. 

The weapon-research software is always dangerous. People have seen how AI can boost weapon development research (R&D). One user has lost the account because of the use of Chat GPT for weapon-making. That person developed the model for an automatized gun. The Open AI didn't tolerate that thing. But the AI is ready for military purposes. The policy is not a good and effective way to deny weapon research. 

The policy can change. Somebody can steal the source code. And then make changes to it. There are hackers in the east, who are ready for that project. They can operate for governments. But people like Mafia can also operate in this kind of project. 

The developers can create "the evil twin" of the famous chatbots. People like Russian oligarchs and mafia have money. They can hire developers to make that kind of software. The fact is that people are afraid that China or North Korea can steal the Chat GPT source code and make necessary changes to it. For making the catapult and other simulations the AI requires access to programs that can handle magnetic simulations. The program that the Chinese published is more effective than HFSS.
