I think that millions of people have worked all their lives with
electronics without even having heard about spice simulators,
These people, and service engineers, and students, amateurs, ham radio
builders, etc will have no problems using EWB, without reading one
single line of docs, without learning anything.
That is the beauty of EWB, people with knowledge about electronics and
using computers can use it straight away, and have a working circuit
within a minute.
To use your program they would need to learn a lot about netlists, and
learn a whole new set of terms and how to use them.
EWB users would be doing spice analysis without even knowing the word
Of course they could do a lot more sophisticated and specialized
simulations if they had that knowledge, but with EWB they at least can
start working with computer simulations without any initial problems.
If you are used to get by with such simple tools as oscilloscopes,
voltmeters, function generators, you feel no need for the more
sophisticated tools your program offers.
A sophisticated spice simulator could very well have such an easy to
use interface even if it also had a lot more sophisticated tools which
the user could learn later.
There is no good reason for omitting the simple user interface when it
is relatively easy to implement.
It would be like writing books with edlin just because nobody bothered
to create a modern text editor.
The first professional spice simulator which offers such a simple
interface will take over a big part of the market.
The potential market is a lot bigger than just the few professional
designers who can use spice simulators without such an interface.
You used the word "must" extensively in your message.
A lot of people would like a world with less "musts" in it.
