It probably has to do with whom you talk to and what sites you frequent. I've seen lots of conspiracy theories about how this was engineered by China in order to crash Western economies with China getting back on its feet first so it could take advantage of the West while we are down. Seriously. I've heard many people saying that social isolation is going to be permanent going forward. I've heard that the government is going to use this to enforce martial law. I've heard that Trump is going to use this to cancel the upcoming election and invoke something or other to put himself into power permanently, a la Putin. Etc. That's just the tip of the iceburg. There are tons of conspiracy theories. I know people who are starting to stockpile guns and ammunition (and probably TP) in insane amounts. I know people who are pulling all of their money out of the banks. I know others that are buying gold. A lot of gold. In my view, people are verging into extreme unreasonableness.
On the other hand, there is the other side of not being reasonable. Yesterday a friend was at the park with her kids. Another mom was on her phone talking to her doctor about her kid's fever and cough. The same kid that she had brought to the public park!
I know people who are planning trips to Hawaii while the kids are on this extended vacation.
There are a lot of people who are not taking this at all seriously.
