The curve is a good abstraction, but it is a partial lie:

"Changing the behavior" and thinking to "what can I do to not infect the others" are the best advice someone can give and should be a moral code for the next couple of years when we are going to deal with the virus. Ultimately, the most realistic scenario seems to be that the virus will become endemic, so until we have efficient vaccines and anti-virals, I expect the world to be in partial lockdown. Initially, Wuhan/Italy scenario, to then relax a bit to China/South Korea scenario, but I don't see the life returning to 2019 for quite a long long time. And until then, everyone should do their share of being careful and changing their behavior.
On a related note, if people minimize going outside, for holidays, etc for the next 2 years or so, I wonder what are gonna be the effects on climate change and the carbon emission reduction.
