It's a mistake to believe that either China's will continue along uninterrupted or that it will fall into severe crisis. The reality is that China has a strong economy AND also a very flawed and troubled economy (India has similar problems but in a different way).

The result will probably be that China's growth will at some point stall out before reaching developed world levels and they will probably be faced with some manner of serious problems at a level less than countrywide existential crisis.

Also, as to "predictions being proven wrong", remember that every year during the 2000s many people predicted that the housing market would implode and lead to a major economic crisis. They were "proven wrong" every year until it actually happened.
