Industrial espionage isn't magic. Airbus once stole basically everything Boeing had, but that doesn't mean Airbus could magically build a better 737 tomorrow.
China steals a lot of documentation from the US but in a tech forum you of all people should be very familiar with how little actual progress a bunch of documentation is towards a finished unit.
The Comac C19 still uses American engines despite all the industrial espionage in the world because most actual engineering is still a brute force affair into finding how things fail and fixing that. That's one of the main advantages SpaceX has proven out with their "eh fuck it, just launch and we will see what breaks" methodology.
Even fraud filled Chinese research makes genuine advancements.
Believing that China, a wealthy nation of over a billion people, with immense unity, nationality, and a regime able to explicitly write blank checks could only possibly beat the US at something by cheating is like, infinite hubris. It's hilarious actually.
I don't know if DeepSeek is actually just a clone of something or a shenanigan, that's possible and China certainly has done those kinds of things before, but to think it's the MOST LIKELY outcome, or to over rely on it in any way is a death sentence. OpenAI claims to have evidence, why do they not show it?
