Of course they will try - they're forced to because a dead or quarantined workforce isn't exactly productive.
But the ongoing incentives have existed for many years, and the numbers of companies supporting true remote working has been essentially a rounding error.
The problem is that these companies are adopting it because they had literally no other choice - not because they wanted to try it - so there's automatic friction there.
I think a lot of society (particularly big city issues) could be reduced greatly if remote working was adopted more broadly, but I've also heard all manner of arguments about why remote working "doesn't work" for the past decade or so I've been doing it.
