This would make sense if it wasn't for the fact that Google (at least my org) is already spread around several offices and project work already happens across different timezones and locations. We have regular meetings with people joining in remotely. I work mostly with people from the other side of the world (despite my immediate team sharing the same city as me), this is because my actual projects don't reflect necessarily my local team composition. We make it work, we've been making it work for the past 2 years and even before the pandemic we had people working remotely. My previous team was split across Europe and NYC and it worked just fine. Honestly, hybrid work with some people being permanently remote and some people working in the office would have very little effect on our already-existing working culture. Just my experience at least.
