Unless you happen to be a dimensional artist ...as in sculpture ...carving...model making..and can understand "depth" and how to use it...

then ...
for everyone else ...
it will be a fancy way of looking at videos, and games and watch in "holograph-i-vision" ...episodes of Mutual of Omaha's "Wild Kingdom" starring Lorne Greene ...
So everyone can enjoy looking at dimensional film of all the future extinct species...

If it works...
and software and progs and apps and content is made for it...
It will be a novelty ...soon to disappear or become just another "function"

But yeah...unless you are a "creator" in the true sense of dimensional art...
It will be useless ...
so it will be something to "watch" and "look" at...and pivot and spin around....and little else for the population...
And THAT means it's shelf life will be short in the attention span of the populace...

The only reason I would want one is to "make" with...
but I wouldn't believe for a second that it will be the "next big thing"
Heard too much of that over my lifetime...
.0001% of such "next big things" make it to become common utility...

But for the general pop.
I wouldn't suggest buying one out of the gate... ...
