Yes, vastly superior, like years, maybe a decade ahead already, and they will only continue to pull further ahead while the west demographics change. I have friends from China, and their families back home are amazed at the conditions of the USA compared to China. Granted, it is Shanghai and the larger areas these people are from, but the USA is becoming primitive v. these areas.
China definitely has quite a bit of high tech that was handed to them by Western multi-nationals or other Western individuals, and they might have even innovated one or two things, but after living there I find it difficult to believe they can implement it large scale the way we do in the West.
The in-joke among foreigners and locals was that Shanghai was so much better than anywhere else in the country that it wasn't even really China. Shanghai is its most advanced city, but I also see the problems that show how inconsistently "advanced" China really is and that much of it is a facade, like the Ghost Cities, the fake GDP based on fake stats, etc.
In 2009 a brand new 13-storey apartment building in Shanghai just fell over on its side while the final inspector was checking it before occupancy, and sadly he perished. https://archive.is/QmiB
There was a high speed rail head-on collision in 2011 in Wenzhou, Zhejiang province, and the govt. literally buried the train cars in an attempt to cover up the story.

I worked in aviation and the young men training to repair aircraft came from families who could afford college, which means out of thousands I knew, only a handful had ever changed a bicylce tire because they had always paid someone else to do that.
None had ever checked the oil of an engine of any kind, and that remained true during their two years in aviation repair college, where they mostly memorized Maoist theory and, despite few of them even being conversational in English, were also required to memorize reams of English text about exotic tools I'd never heard of. There was other, more practical material in the curriculum, like some simulators, but not much.
Next, they got about six months of formal on-the-job training before assignemnt to a crew. I knew one of the crew leaders because he was my landlord back in the city, and he was sharp enough to troubleshoot and repair common problems in some very mature technology.
He explained to me that he supervised by watching everything very closely and that's my admittedly limited understanding of how Chinese technology works: one smart-enough supervisor watching 10-15 guys who can turn a wrench if you tell them exactly where, exactly how, and then double-check their work. But you can't double-check all that work and the results showed it. Western aviation inspectors told me it was just barely good enough to not get failed: C- or D+.
Our inter-dependence on China has resulted in the rising of their quality of living and a lowering of ours, as well as our technological standards, such that we seem to be headed to a final resting place in the middle. While we don't have high speed rail in the USA and there are many other problems, my daily life in a Tier-1 city in China was less technologically advanced than here, and every "advancement" they had contained many frustrating bugs.
But hey, I'm just one guy and that's my take on it.
