@matt you were (are?) extremely concerned about mining centralization and the risks it poses to Bitcoin.  Pierre doesn’t seem terribly concerned. 

Would you review this thread and help me better understand both of these view points?

If I recall you even suggested a nuclear option of changing to another hashing algo if we cannot fix the situation.

Pierre, I respectfully disagree with your position. 

 Your claim was “Until further notice, Bitcoin is NOT censorship resistant.” I think you’ve appropriately backed off that claim to a more nuanced “there’s a risk of Bitcoin maybe not being censorship resistant in the future”
