I think it's a matter of aging. Stuff loses excitement after you've been around it for so many years.
Perhaps it is. When you're a kid, the world is new to you and everything is exciting and has magic to it. As an adult, you become hardened and cynical.
Though it does seem now, a computer is a computer whereas in the 70s, 80s and 90s, computers were more diverse and went through significant changes every few years.
Indeed that is true that modern PCs are just a soulless appliance similar to a toaster or a microwave. However, the hardware is much cheaper and vastly easier to set up and use now. Also thanks to USB, you can buy any peripheral, hook it up, and it just works. In the 80s you'd be like "Oh no I can't use this TRS-80 printer on an IBM PC because it's Centronics standard and I'll produce magic smoke. Oh no, this Commodore printer has a proprietary serial interface. Can't use it." and so on.
Or not having eye-straining CRTs or floppy disks that you can't read in someone else's computer because your drive was out of alignment.
Not everything "just worked" back in the day, and the general feeling among consumers was pure confusion when they wanted to purchase a computer. Not to mention a lot of shonky computer shops who sold you overclocked gear or Cyrix machines, telling you they are "just as good" as the stuff from Intel.
Trying to set up PCs used to be pretty horrible, especially in the early 90s. I have an old book "Secrets of Windows 3.1" and the degree of incompatibility that existed among PC manufacturers then was ridiculous. Things like "Windows may spontaneously reboot on Compaq 286s with the V2.4322a BIOS".
PCs may be soulless appliances now, but for goodness sake at least they work and you don't have to move jumper blocks around or find out that Windows is not compatible with your motherboard.
Just go to Google Groups and find a thread with people whining about the end of gaming in say 1995. That gives some perspective on how pointless and misguided those kinds of thoughts are.
I know that. In the Genesis/SNES days, Usenet was full of crybabies who had Atari 2600s as kids and were like "Games then used to be so much cooler and more imaginative now they're just generic beat-em-ups like Streets of Rage or Street Fighter." Never mind that their nostalgia goggles blocked out the numerous piece of crap Pac-Man and Donkey Kong clones in the early 80s.
