Chicago will never and should never try to compare itself to Silicon Valley, Seattle or any of the other alleged "tech centers" throughout North America. The city's diversified economy is comprised of a completely different kind of DNA.
China was missing from talk at two major conferences in the Bay Area. The Valley doesn't want to admit its tech dominance is being challenged by a country that just a few years was a manufacturer, not an inventor.
MySpace and Facebook have utterly failed to improve any significant aspect of the American economy -- and have "succeeded" at wasting millions of manhours that could have gone toward boosting our national productivity.
