Okay, so if and when that happens, get excited about it _then_?

Re the Covid metaphor; that only works because Covid was the pandemic that did break out. It is arguably the first one in a century to do so. Most putative pandemics actually come to very little (see SARS1, various candidate pandemic flus, the mpox outbreak, various Ebola outbreaks, and so on). Not to say we shouldn’t be alarmed by them, of course, but “one thing really blew up, therefore all things will blow up” isn’t a reasonable thought process.
