The delta is pretty obvious, though. Companies that aren't in tech hubs no longer have to hire from a limited local talent pool, and companies that are in tech hubs can save on both office and salary expenses by hiring across the country. I've already seen local companies announce permanent hybrid models due to the former and large Silicon Valley unicorns like Coinbase announce permanent hybrid models due to the latter. And speaking very anecdotally, where I work we've done plenty of surveys on WFH and the results were very clear: not allowing any kind of hybrid model would've become a retention disaster over time. The desire for at least some kind of flexibility post-pandemic was overwhelming.
