I don't think you're addressing OPs point at all. They pointed out that the US currently does have the lead in the field due to its larger prosperity for the most part, but that China is rapidly developing more talent.
What we should copy is thus not the technical status quo, but our attitude towards education and talent acquisition in the relevant fields.Technical advantages are not self-perpetuating. If the West grows complacent and does not develop the talent necessary to advance the research, then that lead will reverse.
