>All the tech for remote work is here already
I'm not sure collaboration software/hardware is really there yet. It incrementally improves and at least part of the problem is probably getting widespread adoption of some specific solutions.
But working on something collaboratively in a conference room versus remotely is still a lot better for certain things. Mind you, I don't think tech can ever get all the way there for some purposes but it feels as if we can still do better than we do.
