Not sure why you're getting down voted to hell. I don't understand why people refuse to believe there is anything beneficial to human collaboration about being in person. It was a lot easier to help out teammates for a 10 or 15 minutes chat near a communal white board or on pen and paper as opposed to scheduling a virtual video call, and creating a diagram in power point or lucid chart in advance for something I could sketch by hand in 60 seconds in real time. Also those discussions did lead to SMEs overhearing and dropping in to provide additional help were great. Unfortunately this hybrid choose your own home or office location is just the worst of both worlds for those that come in.
