My dear friend Prof. Zhang Weiwei debated with Geoffrey Sachs at Fudan University yesterday.
As a warm-up, the professor threw me into the line of fire, so I tried, impromptu, to cross-reference between the elections in Brazil and the USA.
Then Geoffrey gave a master class on Eurasian sustainability, spanning 3,000 years.
At lunch, with other Foden professors, we all tore apart the hard geopolitics, big time.
Shanghai totally rocks.
