It's a self-serving article by the corporate elites to get people comfortable with the idea of returning to the office. Some VP is gonna point to these types of articles and say covid is no longer an issue, back to works guys.
Kinda how like Zuckerberg recently pointed to bogus 'reports' on in-office workers being more productive than remote workers, and then used it as an excuse to RTO. Except it's funnier in that case since Meta is all about the metaverse and being remote, so it's kinda ironic.
