XR is the unavoidable future, whether we want it or not. It is mind blowing to be able to dance with life-sized 3D models. Imagine when we cannot tell the difference between what’s in the headset and what isn’t. Not too far away.

I personally believe that the gap to a life-like virtual experience will be closed with the use of neural networks generating the experience. I also believe that's a long way off.

Reminds me a bit of 'photorealistic cg'. The gap between close and indistinguishable has an exponential curve of effort required. I remember when Final Fantasy the Spirits Within was released in 2001[1], and it was said to be extremely photorealistic. It was good for it's time, but you wouldn't think it was anywhere close to believable by today's standard. That was 20 years ago and still I don't think I've seen a full CG movie that I thought was real.

So my take is that, without the help of AI filling in the exponential curve in ways we've not yet seen, it's longer than we think.
