I don't think we are disagreeing that much. I never said China was ahead of the US overall, but I said they have become ahead in a significant amount of key areas.
As far as money printing, I think both you and I know that the USD's place as a reserve currency gives it enormous leverage to print money with abandon despite never being able to balance a budget. In comparison, China is the world's largest creditor nation and the US is the world's largest debtor nation. That is a huge fundamental difference when we are discussing the financial health of both countries. Economic gravity always shifts towards those who are creditors.
I said China is ahead in quantum communications, which is true. As far as quantum computing, I think the field is young and it is unclear which country is ahead at this time. Both countries have made major breakthroughs but neither have produced a final product.

As far as super computers, I am not sure if you know this but because of the tech war, China has stopped reporting on the efficacies of its super computers as to not alarm the US of its progress. You can call it sneaky, but it is what it is. The word is though that China is ahead and is working on 3 exascale computers at an earlier timeline than the US. BTW 312 of the top 500 systems are now Chinese. Just 10 years ago, China's presence on that list was negligible. This just points to how exponentially fast China's rise is.
Chinese manufacturers continue to dominate the list of makers of the world's fastest supercomputers in terms of the number of systems, according to Top500, an authoritative ranking on supercomputers globally.

Again, the US still retains the lead overall because of a massive head start. But China is rapidly climbing up the charts and at this point should be considered a peer competitor.
