Until substantially more people join the fight for privacy or something else fundamentally changes, I think there is a very real possibility of Google completely clamping down on Android while governments and workplaces mandate apps that only run on phones with all of Google or Apple's bells and whistles.
But the folks at GrapheneOS, Calyx, and Murena seem to be a devoted and resourceful bunch, so I am hopeful that they can give something for us to work with, even if Google pulls the plug, whether it's a fork of Android or rebasing to mobile Linux.
If that all falls through, I'll look for whichever phone supports Linux best and eventually move everything over. The vast majority of the apps I use regularly on my GrapheneOS phone aren't very demanding and have a decent alternative on Linux. And whatever apps are forced on me by other people will reside on a dedicated Android phone, ideally with a removable battery.
For this year, I'd still recommend a secondhand or reseller Pixel with GrapheneOS. Everything just works on it.
