Good analysis. I think the main problem of today is that there is no need for being a "hacker" anymore.
The ancients here will remember how it was vital for them to be "hardware hackers". Because a computer, that was something IBM built, that filled storage rooms and that NASA could afford. If you wanted one, you built your own. Out of necessity. It was either impossible to get one, or at the very least impossible to afford one.
Fast forward to the 70s and 80s, when computers became more or less portable little things you would plug into a TV. We didn't have to solder our own boards together anymore, but programs was a different matter. We had to know quite a bit about programming, even if we weren't into it, for some of the more important tasks were only possible if you at least understood what's going on inside your machine. Not to mention that nearly all of them came with some kind of "user port", where the user could plug in
90s and 2000 brought the internet, along with having to learn a bit about TCP/IP if you wanted to actually get anywhere. Let's face it, Windows was not really too keen on letting you connect to the internet without jumping through more hoops than should be necessary, and trumpet was to us far more than just an instrument.
What these eras have in common was that you had to learn something to get somewhere. In the stone age of computing, you actually had to learn how to build such a machine. And I'm not talking about "putting a CPU without accident into its socket". Later you had to understand the machine's language and had to be able to program, at least a bit, if you wanted to get anything. The early years of the internet meant for you to learn a thing or two about networking if you wanted to succeed.
Today, we transcended it all. Nothing is necessary anymore. NO knowledge, no information, for everything there is a "wizard". Our kids aren't learning anything anymore, and I could hardly blame them. Would I have learned how to build a computer if I didn't have to? Unlikely.
We're also at the point where anything big can only be done with a LOT of manpower behind it, and everything small can be bought for a few cents from China. There simply is no reason anymore for anyone to learn anything about the machines he uses. Unless, of course, he'd be interested in it.
