I was less worried about it at the beginning - I think I had a decent understanding of how fatal it was, but underestimated how contagious it was.
I think I came around to a mental model of how to react fairly early on, though. The basic model was stay at home until either a vaccine arrives or until we have anti-viral treatments that reduce severity and improve outcomes. Neither has happened, so I'm in the same boat.
It's great - great - that the lockdown has reduced occurrences of it so much. And I recognize the argument that if we've tamped down on it enough, that it's safer to go out there. But... an x% less likelihood of catching it doesn't mean it will be x% less severe when you do catch it. I think that a lot of non-technical people are confused on that point.
And finally, even if we did have really good contact-tracing... that doesn't help you, it only helps your friends. There are still those two days when people are contagious without being symptomatic. That's just still reality, I don't see a way around that. A healthy people can die from interacting with a seemingly healthy person.
Besides, what happened to contact tracing anyway? I thought we were going to have this snazzy contact-tracing tech on our phones and watches by now, courtesy of Apple and Google. I'm sure our contact-tracing is still lousy overall. It's great we have more tests, but we're not at the point where we would have been able to stop February in its tracks.
So overall... yeah, I've changed my minds in ways, like recognizing that the probabilities are more on my side than they used to be, so I feel a little safer if I have to go to the doctor/dentist for non-COVID reasons. But other than that, it's still a super-contagious virus that has a decent chance of really screwing up your life even if you aren't 80+, so... I'm still in the "stay at home until treatment/virus improves" camp.
