I don't think that's a counterpoint. It depends on executives continuing to believe F2F is superior.
The evidence already existed that WFH is, generally, better. See Stanford's Bloom 2013.
But executives are afraid to take big risks like that. They doubt studies. They overindex on personal experience. Which this gave them.
Now that they see what WFH actually produces, their worldview shifts to what was already true. You get talent that's more productive. Lower costs so you can afford more talent, or, alternatively, more expensive talent. Fewer geographic restrictions so you can recruit a bigger pool of talent.
Once you're convinced WFH works, these advantages can give competition an edge. An executive doesn't want to be on the wrong side of that edge.
But they have to see it first.
There's no reason they go back to thinking F2F is better, unless it actually is, and currently no evidence suggests that is true.
