"Researchers" (people with a technical interest on the subject vs.
"artists" or those with only an artistic interest) understand that
stereoscopic imaging is based on presenting "slightly different" images to
each eye. This can be done using some device like a stereoscope, or using
polarized light, or alternating liquid shutters, or by training the eyes to
be directed to each image without external help ("freeviewing").  I don't
think any "researcher" will ever say that you need a stereoscope to view
stereoscopic images. 

But in order for me to explain to most people what they are missing by not
being able to train their eyes to see the "stereograms", I copy them in
slides and present them using a stereoscope (Realist "red button" viewer)
or in projection.

So how does the future now look after the "stereograms"?  Where are those
millions of people who's lives got affected by these "stereograms"?

No, they have no idea what you are talking about.  This is a visual
experience.  If they have not experienced a stereogram then they have no
clue what stereo and freeviewing is all about.  That's why I copy those 
and present them with a stereoscope.  To show them what this is all about.

You make a very good "motivational speaker".  Unfortunately, I am not the
kind of person who is motivated by "speeches" like this.  I work with
metals and materials.  My relatives ask me when I am going to invent the
wonder-metal that is tough and formable at the same time and carries other
wonderful properties too.  I try to explain that it is much easier to dream
about it than actually make it at a competitive cost.
