I think it's safe to say we are witnessing a truly historical event unfolding. There's real anxiety about economic and human impacts. It's right to be concerned. We may be about to experience trying times neither of us have seen in our lifetimes.
We all need to acknowledge that, and keep calm. Panicking and ignoring the problem is (I believe) two different extremes. Rational and clear headed thinking is the mean between those extremes.
Don't forget that America does its best when our backs are against the wall, or facing extreme adversity. We have a history of innovating and pivoting in response to huge obstacles, and I see no reason to believe this time will be different.
