It’s true enough that we do live in the present, but it doesn’t strike me as being prudent to completely ignore the lessons of the past. “It hasn’t happened yet” isn’t a strong argument for “you might as well have a good time now and not worry about the future”. Especially when it has happened before.
I’ll bet there’s at least some percentage of the folks who have lost everything in the last year who would like to reconsider some of their past decisions.
