Of course computers (including mobiles and tablets) became widely mainstream over the years so the percentage of tinkers dropped but the absolute numbers increased.
Really though, the RPi's config.txt is exactly this kind of rabbit hole. I just got a Zero W today and now I'm thinking about if it's possible to underclock it enough to power it with a lemon battery via GPIO.
According to this video I’d need a wall of lemons to get 5V with support for 300mA of current: https://youtu.be/a1D-fZP8qJk?t=205
So it may take some... adjustments... to get something like this to work, but I’ll see what I can do.
It used to have significantly more performance problems, but it's always followed the basic form of "tiny PC with IO pins and overbearing GPU".
What did your elders who grew up with books and radios say of the early computers era you’re fond of?
A book still smells like a book.
You can still buy beautiful books.
In fact, I don't see the difference between the books from my youth and the books now as an adult.
But the IT field is certainly very different.
However, I don't miss the old modems, the hacks to get my maxtor working, clone CD and emule. I don't miss the floppy, black and white low res monitor, the clunky hardware and the slow or no internet.
I like HD. I like thin laptops, WIFI, USB, bittorrent, and a usable linux desktop.
I do have nostalgia for how the discovery of the old internet felt, the sense of community, the ethics and dreams. But it doesn't mean the current one is not awesome.
There are all sorts of electronics besides computers. A CPU is a very small shrunken sets of transistors that are too small for anyone to interact with other than through software (realistically that is). However, older "computer" devices used components large enough you could see and manipulate by hand. The traces on the boards were large enough you could physically scratch/break, and re-wire (reprogramming) causing the device to do something new. To the point, at some stage, stickers reading "No user servicable parts inside" became a thing so people would stop tinkering. That sticker has now been replaced with an apple shaped logo, but they pretty much mean the same thing now.
