I've experienced full "embodiment" with top end room-scale equipment. It's pretty cool, but it's nothing life changing, and certainly doesn't deserve the hype that is thankfully now starting to die down. I largely agree with the author.
And even in our early exploration there's already huge variety, from e.g. spatial CAD to novel social formats to new physical/coordination skill based games, virtual theaters, educational tools etc.
There is a wide range in how much being embodied is going to matter depending what you're doing in software. I think for an artist virtually sculpting 3d works it's not a stretch to say this could be life-changing, for example.
My guess is that very few watchers would prefer a 3d reenactment over the 2d original stream, as the reenactment will always have less details or even show things incorrectly.
