I am no longer claiming that the Chinese are now the equals of the American engineer in the 1950's. It is not true. From what I have seen lately I can say unequivocally that American engineers were never as good as this, not even at the nadir of their culture in 1955.
Some of the structures I have seen photographs of in recent years indicate to me that the Chinese have pioneered a new understanding of load bearing megalithic structures that is unprecedented in recorded history. The Kwanstain cannot even look back to former glories to compare with these.
