The fact that Chinese gear like the CH-4, FN-6, and other weapons have performed well under combat conditions offers a pretty good gauge for the state of Chinese military development. I think that once Chinese fighter aircraft like the J-10 or JF-17 (technically has an aerial kill against a drone) accrue real life combat experience, some of the prejudice against Chinese aerospace capabilities will subside.
I don't think so for two reasons.
1. The prejudice is not one that is naturally arisen from observation but it is one artificially fabricated. (For example, the prejudice that East Asian athletes are poor sprinters is one made from observation.) The former prejudice can be alleviated with contradicting observation and evidence while the latter is immune. (If in the next 4 Olympic cycles, both the 100m and 200m dash finals were filled with 6 or 7 Asians with all medals staying among China/Japan/Korea, that prejudice would likely go away.) The latter is made psychologically; if you really want to believe something, you will find a way to convince yourself and the more you say it, the more it feels like truth, and it will be propagated that way. Because the West has a morbid fear of being relegated by resurgence of Chinese technology, they want to find any way of convincing themselves that Chinese technology is poor (ie. if 10 Western drones crashed, they will say it is unpredictable systems error; if 1 Chinese drone crashed, it is evidence of poor quality) and they will say that lie again and again and hear it from each other so it sounds like it's the truth. After all, China has already shown dominance or at least great competence in many key technologies and most of the super-performers in US universities at math and sciences are Chinese so what objective observation could they have used to create that prejudice? If anything, by observation, they would conclude the reverse. So this type of prejudice cannot be countered by evidence because it was not made by evidence; this type can only be unmade the way it is made, by alleviating the fear that China would overtake them. And I think the only way to do that is for China to overtake them by so much, that they give up and laugh at themselves. No joking at all.
2. Secondly, the West is not impartial to this prejudice; they are served by it and thus will not let it dissipate even for truth. The key selling point of Western goods (including military hardware) is that despite being expensive, they are perceived to be of higher quality. So long as this prejudice helps their businesses, the West will desperately want to keep it in play to protect their livelihoods and wealth. If they let it die simply because it is not true, then what business is there left to do? You're admitting to the world that you are selling comparable or inferior goods to the Chinese at higher prices; game over. In self-interest, Western countries won't even buy from each other if the prejudice against Chinese quality were to be eliminated. Thus, by any means, media, false interpretations, fabrication, etc..., they must keep this force in play. Even when Chinese drones reported 100% success by its client, Americans still said that US drones are better because the Reaper has flown over 5 million hours and Israelis said that theirs are better because "You can't shortcut 40 years into 5 years." These statements don't even make sense as testaments to capability/reliability but they still have to say
something to prevent the conclusion that Chinese drones are of at least comparable quality. Just like Ford and Chevrolet can never admit that the other can make better cars no matter, the West can never admit that Chinese quality can match.surpass their own. It is a matter of survival, not honesty.
