We’ll implement systems to prevent this from happening again. My prediction is that one (or several) of three things will happen:

1. We will learn overly-specific lessons from this. For example, we might blame China, and put sanctions on them until they permanently close down open air markets. Lessons like that might have stopped this disease, but they won’t stop the next one.
   
2. Related to the above: we won’t agree about how to prevent this from happening again. We’ll do the best we can, but our fixes will be a muddled mess, at best.
   
3. Once our fixes are in place, we won’t forget this, those of us who live through it. But we’ll die, and be replaced by people for whom all of this is just history. They won’t feel the urgency of our fixes. They will see our caution as unwarranted and overly-fearful. Over time, they’ll dismantle our fixes. This is the problem with “never forget”. We don’t, but sooner or later, most people never experienced it to begin with.
