A lot of this is driven by capitalism's need for obsolescence, and how it gets refracted into digital spaces. Since the corporate media makes money on eyeballs, we have to move on from COVID once it reaches saturation, because it doesn't help sell anything after a while. What constitutes "now" gets shorter and shorter. General relevance for content used to be 1-2 years. Now almost nobody will read anything older than two weeks, because its framing assumptions are considered no longer sufficiently timely.
