Competition is great but when the narrative starts leaning towards "Us vs Them" and "We are at war" and countries start actively sabotaging each other, then we have a problem.
This competition has been going on quite a while. Is there any evidence it has led to any of that?
With China? Maybe not sabotage, but IP theft and espionage. With Russia? Certainly.
People steal technology because someone else’s is better and it’s cheaper than doing the R&D yourself. If the US just quietly made better computers and there was no ranking, I’m certain China and Russia would still be stealing IP.
