Easy now.  I haven't commented on your English.  And I won't, since I don't 
really have a second language. You are ahead of me there.

People create models of things they don't understand all the time.  That's 
what models are for.  Back a ways in times when the earth had to be the 
center of everything, orbits of the sun and planets were described by the 
"experts" of the day using systems of wheels whose axles were on other 
wheels.  Turned out not to be true, they clearly did not understand reality. 
What gets lost in that dismissal of method is how well the system of circles 
(a model) predicted where everything would be seen in the night sky, for the 
accuracy of measurements obtainable in that time.

The worth of a model derives from how well it predicts what will happen when 
something is actually constructed, not how long it has been around.   I 
repectfully decline to air my thoughts on Microwave Office...

It's a dangerous thing to speculate on another's expertise or lack of it 
when one does not really know the person behind the "pen".   You might be 
right, or you might be ghastly wrong.  As to what you're building, I'm 
always ready to hear about something new.  Go for it.
