I'm the same way, and it makes me feel a little sad to think about it, and even more sad when I try futilely to get back to that same understanding only to realize so much of the mathematical foundation required to understand them vacated my brain long ago as well. I suspect a lot of EE majors who actually bothered to really understand them at the time feel the same way.
Do you remember feeling like you used to love what you do because of that sort of understanding and the ability to observe it in the world around you? Pepperidge Farm... er... perldigious remembers. Successfully bringing a practical design to fruition is a good feeling, but it only took me a few years out of college to figure out that the bulk of my career as an EE would instead be spent doing tedious paperwork, dealing with corporate bureaucracy and politics, and constantly trying to appease various members of $management who often have completely conflicting goals and nearly all of whom ultimately only have the goal of staying in power or acquiring more.
That last link is sort of long, but it's very good and he ties everything back to business and the general world outside of politics at the end. My friend sent it to me when I was lamenting to him that, "I just want autonomy, freedom over myself, and I just don't get why the overwhelming majority of people in the world seem to want authority over others. So yes, I do have an 'authority problem', the authorities in question are just framing the problem differently than me. If one of them tells me to jump off the building with nothing but an umbrella to break my fall, I'm going to insist they 'lead by example' first to get my 'buy in'."
Just another Perl hooker - My clients appreciate that I keep my code clean but my comments dirty.
