Yawn. Kids these days. Yes, the technology has changed, but the practicalities and bureaucracies have not.
When I first got into ham radio, a half dozen guys who were interested would gather together in basements and garages to build ham radio satellites. One of those creations is still functioning today, decades after it was first launched (OSCAR 7). The technical challenge of building to a clean sheet of paper is interesting and instructive. However, it is trivial, especially when dealing with something that is basically a one-of creation. More to the point, they didn't have professors telling them how it should be built. They just did it using the technical papers published from the earliest spacecraft experience, their own educated guesses, and practical know-how.
I had many mentors in my ham radio experience. Most hams these days are happy just to know how to assemble a station. I went beyond that. I had experience working in a two-way radio repair shop. I had help designing microwave radios, spread spectrum systems (long before the IEEE 802.11 standards), packet radio, and so on. I did this in 1980 and 1981 as a junior and a senior in high school. I built a crystal phase-locked 10.250 GHz transceiver. I had an early packet radio system built around the W0RLI Terminal Node Controller. I studied electronic warfare systems in my summer internship at Naval Research Lab. I studied and constructed experiments in audio compandering, narrow band integration of slow CW signals, early micro-processor systems, and many other things. By the time I got to college, I'd already seen and done many times more than most people would ever get in their entire college experience.
Yes, some of the finer points of semiconductor physics were interesting. The Fluid dynamics class was interesting too. However, the math was mostly stuff I'd already seen in another form. The signals class would have been much more interesting if the instructor were worth anything. Thankfully I had a lot of practical intuition from my earlier experience to throw at that class that got me through it.
However, today, when designing half a dozen chemical feed systems for a large water treatment plant that must be reliable, economical, intrinsically safe, secure from cyber attack, coordinated with concurrent projects, integrated into existing control systems, and built on existing infrastructure --that's a completely different issue. In many ways it is far more difficult than putting a satellite in space.
By the way, that's a small project. Don't get me started on what larger ones are like. The technical part is often the easiest and simplest aspect to all this. It's the other stuff that tends to drive everyone nuts. THAT is why it takes so long to bring a graduate up to speed.
Those of you who think that Engineering is all technical are living in a dream world. If it were just technical schools might not be so far up the back side of the power curve. It's the social and decision making processes that are most daunting. I have yet to find a school that can teach those things.
