I see three assumptions in your paragraph that need to be true in order for the technology to work. I'm ordering them by how likely I think they are to come true in the next decade.

* Headsets will have good enough resolution and be generally comfortable enough to replace monitors for office space.

* There is a solution to the pass through input problem that is acceptable for the average office worker. I don't think there is a solution of the passthrough problem that beats a keyboard/mouse, or even a laptop in a cafe. I think it's more likely the average office worker will accept a worse form of text input given the right conditions.

* It's possible to project a 3d image of myself while wearing a headset that doesn't include the headset and passes the uncanny valley. The uncanny valley is wide, and even AAA video games haven't cleared it yet.
