I know what a rebuilt city looks like, because I come from one. Hurricane Katrina was 2005. Christchurch Earthquake was 2011. In my opinion, my home town has recovered better and faster from destruction than New Orleans has.
I also live within a floodzone. There is a high probability I will learn how we deal with flooding in the future (different flooding - shallower and lacking the winds and hopefully better pre-planning for avoiding harm).
> everything looked brand new
Absolutely not, to me.
And the conversation is regarding infrastructure. A bunch of Christchurch infrastructure is brand new.
