TL;DR

For me, VR/AR will become useful when telepresence is useful for me.

E.G., when I can send a drone out to scan around my property, or check for the location of a tool or supply item in my shop, without having to walk out there.

That may sound like laziness, but my health makes walking the mile to my back acreage a chore, and half the year the weather is lousy (rain/snow/wind). It would save me a lot of time and enable me to do things I don't do (check for trespassers or other dangers - e.g., forest fire) because of effort and time.

I can think of a number of other beneficial use cases of telepresence - and I am not talking about avatars and some kind of virtual "metaverse".
