Hybrid done wrong is the worst of both. To say people must be in a particular office X days a week causes an organization to both be limited to local labor pools, plus have not only the headaches of remote, but also the even larger headaches of trying to run local and remote hybrid meetings. Some organizations will find it too hard to pull off, think that remote is only a perk for employees and call everyone back to the office fulltime. This will destroy work life balance people worked put working remotely. With that will come even further slowing down of replacing people who left. One can say to just tun the meetings remotely, but aren't the meeting in person why organizations have people in offices?
I you haven't checked out Elaine Pofeldt's work, you should. One interesting phenomenon emerging from the convergence of these trends is businesses with one primary employee that generate over a million dollars a year in revenue. This is enabled by leaner, just-in-time manufacturing, far bigger marketing channels, platforms like Upwork for hiring people to do one-off tasks, and the like.
