I think it depends on your industry and specialty. In my line of work my coworkers are all over the world and can't really be centralized. There may be clusters in different regions, but it's hard to justify (in my opinion) coming into the office to see two colleagues you may not even need to talk to that week. It is especially more difficult when meetings are regularly outside of normal work hours.

My company is still trying to force people back in where there are clusters, but I feel like they're spending more on bullshit events to make it seem like it's worth it than they could possibly gain in productivity. It really feels like a bunch of people trying to justify their jobs than anything else.
