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.
But from his point of view, I was asking him if he believes that it would be rational to start clamoring for a POW-change.
It is kinda hard to hide something of that scale, in case a prominent member of the Chinese mining community such as Jihan Wu (or anyone else for that matter) is threatened with prison time. Something is going to leak out.
The Chinese government could order to cut all electricity to all mining farms in their country immediately. Should we start clamoring for a POW-change?
