Then do you truly believe that we should start clamoring for a POW-change? The Chinese government can do it anytime they want, you know. 
There's difference clamoring for PoW algorithm change and preparing for worst case scenario which forcing PoW algorithm change.
If Bitcoin community could agree on few critical things (which PoW algorithm should be used and should the hard-fork include other changes as well) for worst case scenario, it would significant decrease damage if such worst case scenario happened.
