I'm still quite amused by the current crop of "hackers" who think they're all that but never built their own computer from chips and raw PC boards. Building a PC these days is something grade school kids can do.
I've been thinking that for a long time now, even though I didn't start that far back myself.
I started with the z80-based ZX Spectrum, and then graduated through a series of early PCs. The earliest one running GEM with a hercules (monochrome) graphics card.
As there wasn't much real software about then if you wanted it you wrote it yourself, reading the programming guides, and Ralf Browns' interrupt list.
These days there are people grown up who've never known anything before Windows 95; they grew up with the GUI and an environment which just worked. They never had to tinker, they never understood from the ground up how the PC works, and have little incentive to experiment. Back in my own personal olden days you had debug, you had built in support for programming. Nowadays its' all hidden away.
Don't even get me started on people who don't understand what pointers are, or how they work...
