There's another plane on which the analogy fails: the first generation of PC enthusiasts were working with a genuinely new thing. The consumer/hobbyist-grade hardware that the introduction of the 4004/8008/6502 made possible was quite literally impossible only a few years prior. And there was good competition (OK, we Apple ][ folks despised the 'Trash-80', and everyone looked askance when the Commodore 64 with its glitzy marketing toward people who didn't even own soldering irons showed up, but we peripherally recognized each other as factions of the same tribe, and there were options).

Neither of those things is true of the Arduino. I learned how to design simple control systems on Microsequence Controllers ancestral to the AVR more than thirty years ago. And the techniques I learned there still apply to the more sophisticated chips available now. Even the hobbyist platform stuff isn't new. I was wire-wrapping DIP 650*'s into perf-board in the early 1990's, and I built an HC11 model rocket launch controller for my kid the better part of two decades ago. And I know more than a dozen people, not all of them professional engineers, many with only two-year college diplomas who were doing sophisticated hobbyist projects well before the turn of the millennium.

The Arduino isn't analogous to the Apple ][. We had to learn how to program in BASIC and needed to know what a memory map was. It's analogous to Windows 95: a well-engineered product that completely dominates the market, establishes that you don't really need to know anything, and stifles innovation.
