Well, LaTeX isn't a UI, it is just a set of macros to make things 
easier. For instance, in TeX you might have to do some crazy thing 


to get a particular set of text typeset a certain way, while LaTeX 
just takes the most useful of these commands and makes them into 
macros like:


What you lose is that there are lots of small changes you could do in 
TeX to specifically alter the typeset output, while you are stuck with 
the way the macro does it in LaTeX. However, most of these changes are 
probably so subtle that only an expert typesetter would notice the 
differences, so for someone like me, LaTeX has plenty of control.
    I would imagine that LyX doesn't work directly with TeX because 
they would just end up redifining the macros all over again in a 
similar way to LaTeX. Why bother to do this when you can use an 
exisiting popular system? Sure, if they started from TeX they would 
probably make things a little different, but then you would spend a 
ton of time, and also lose all of the nice packages that have already 
been written to use with LaTeX. Plus LaTeX is sooooo damn nice :-)

I think that both LaTeX and TeX always just use a .tex extension. 
Since the underlying typsetting program in TeX in both cases, the 
program just has to know whether it needs to expand LaTeX macros or 
not. It is actually incredibly easy to tell the difference between 
documents and plain TeX and LaTeX so I don't think having different 
extensions is really needed.

But of course -> http://www.kfa-juelich.de/isr/1/texconv/texcnv.html.
