I very much disagree. The mistakes that were previously made (both broadly socially and specific instances, such as closing the pandemic response team and the delay in testing) were all incredibly foreseeable. I find it the height of dishonesty to say "Gosh, we had no idea what would have happened, we just have to focus on the present". Now, I don't think you're saying that, and you're right that the current situation is where we are and we should focus on what we can actually do. In the "never let a good crisis go to waste" vein, though, one thing we can actually do is make people realize that the health and well-being of your neighbors is inextricably linked to your own.
