Due to human nature usually 100% of the participants will elect to NOT to be shown on video, (although they could) as most people just don't want to share what they look like at their kitchen table at 9 am during a live call. Your scenario has holographs sitting down next to other holograms and shaking each others hands and registering pressure and feeling to those participating? I can see other use cases for that technology but for a business meeting that's overkill. Technology like that is outright creepy. I will stick to my webex meetings, and having my outlook calendar reminding me of my day's meetings. No virtual assistants required. Call me outdated but people still read actual printed books as well.
