The opening line: "To prevent future pandemics, it is important that we understand whether SARS-CoV-2 spilled over directly from animals to people, or indirectly in a laboratory accident." Is that true? I mean I understand why people would be curious, but does it really matter, in terms of what we need to do? We know that viruses _can_ spillover from animals to people, and we know that viruses in a laboratory setting…
Obviously if it is possible that COVID came from a lab then we should act as though it did - the best case is these labs are catastrophes still waiting to happen. And I suspect so is the web of international travel we've built up over the last few decades.
But at a population level, the human race can't process the implications of that. People are profoundly evidence based - we won't see action until there is evidence that a risk is manifesting. Which is possibly why people care about whether COVID originated in a lab or outside one.
