Tools are great, I use them myself. But you have to have some knowledge of
what's going on to know when the answer the tool gives you is wrong (maybe
you didn't feed the tool enough information, forgot something, or there is a
bug in the program, etc). Lots of solutions that look good on a computer end
up not working great in the field because of many things that are not
modeled in your tool. Bridges fall, roofs cave in, microchips short out, etc
not because the tools were wrong, but because when things get too big or too
small other forces that normally don't matter come into play. The only thing
that really changes in engineering is we have new materials, controls, and
better detailed models to play with, the basics you learned in school don't
change much if at all. Without the basics the tools are just a good quick
way to make a mess of things. Somebody who knows what's going on can jump
from tool to tool, if you just know how to use one particular tool then your
in trouble.
The most important things I learned in college is how to deal with people
you might not like but have to work with, the basics of the field I was in
(that you DO use believe it or not for the rest of your life), and how to
solve problems you never seen before in a logical way. The fringe classes I
took in college might not have been directly used by me in my job, but they
were useful in giving me a perspective of what the other disciplines needed
to know from me to get their part of the job done.
Specialization is ok if you like doing just one thing and don't mind being
out of a profession when your specialty is obsolete (especially in any
programming or electronics field).
A few people do know what the chip in a video cards does step by step, if
they didn't they could not design the part to begin with. Just because there
are a million gates in the part doesn't mean each one is doing something
totally different. Tools just do the time consuming calculations, you still
have to tell them step by step what to do so I would not say they do all the
thinking. Then you have the fun of taking your model and figuring out a way
to build, control, repair, and package it which is a whole job in itself.
