Yes, we've all seen it. Honestly can we just discuss the tech for once instead of making the same comment 30 times on every Google thread?
This sort of video streaming is reminiscent of the "tele-human" teleconferencing in Silicon Valley [1]. Hopefully it works better. It would be timed well as so many companies are looking at working from home right now. Though as with anything with "Project" in the name, I wouldn't expect any actual product for at least five years, and probably more.
Salesforce makes sense as a partner. They have multiple global offices and could stress test things beyond internal dogfooding.
