Could we actually come out this crisis changed into something new? Short answer: no.
It's because we all fall in different places on the scale of how we live our lives. We range from those who religiously plan in advance to those who just cross bridges when they come to them. From those who extrapolate from the experiences of others to those who only relate to stuff that actually happens to them. From those who think we have a measure of control over our lives to those who think our lives are preordained. Sure, short term we'll see people live differently, just like after 9/11. But I can't think of any experience that will change human nature.
