I couldn't argue with any of that. Again, there are exceptions on either side.

I don't think it's an age thing, though.

The number of people who have a real interest in technology, and how
things work "under the hood" hasn't changed much.  I know people 10
years younger than me who can keep up with the best of us, and people
10 years older who are complete failures at technology.  People like
us have always been a fairly small number.

What has changed, though, is that there are a lot more young people
who think they have technology skills; perhaps as a side effect of
growing up in a world where the Internet has always been there.
Naturally, we have a lot of people filling IT spots that aren't
qualified and lack the basic knowledge of how complex systems are
built.   To troubleshoot effectively, you need to be able to break
down systems into their components and isolate the problem; and a lot
of people just don't have the background to be able to do that because
they never cared to do so.  It's just a paycheck to them.

Those of us in my age group were lucky enough to be around for the
transition from dial-up BBS, to dial-up Internet, to broadband.  As a
networking geek I don't think I could ask for a better year to be
born, really.  It's always been exciting.

These days I'm playing with DWDM and a state wide R&E network in a
state that established dark fiber as a public utility; doesn't get
much better than that.

I'd say the future is pretty bright. ;-)

Let me simplify that. If you are over 35 you know how to troubleshoot.

Yes, I'm going to get flamed. Yes, there are exceptions in both
directions.

At the same time, it's shocking how many network people I come across
with no real grasp of even what OSI means by each layer, even if it's
only in theory.  Just having a grasp of that makes all the world of
difference when it comes to troubleshooting.  Start at layer 1 and work
upwards (unless you're able to make appropriate intuitive leaps.) Is it
physically connected? Are the link lights flashing? Can traffic route
to
it, etc. etc.
I wouldn't call it a "misconception", but I want to echo Paul's
comment.  I would venture over 90% of the engineers I work with
have no idea how to troubleshoot properly.  Thinking back to my own
education, I don't recall anyone in highschool or college attempting
to teach troubleshooting skills.  Most classes teach you how to
build things, not deal with them when they are broken.

The basic skills are probably obvious to someone who might design
course material if they sat down and thought about how to teach
troubleshooting.  However, there is one area that may not be obvious.
There's also a group management problem.  Many times troubleshooting
is done with multiple folks on the phone (say, customer, ISP and
vendor).  Not only do you have to know how to troubleshoot, but how
to get everyone on the same page so every possible cause isn't
tested 3 times.

I think all college level courses should include a "break/fix"
exercise/module after learning how to build something, and much of that
should be done in a group enviornment.
