You were a nerd interested in computers. They still exist in younger generations. Just became way less common because the necessity disappeared for most people. Most prefer computers (or any device or tech really) that "just works". Some are interested in how things work. 90% of Lemmy is the latter, from all generations but many in their 30s and 40s because that was peak computer learning age: rather cheap hardware, software still needed to be hacked together somewhat, clear rewards when doing so (for example messing with game settings IRQ etc to get it running).

I've met people born late 90s early 00s doing PhD in computer science who barely seem to know basic general computer stuff... All they know is that one extremely niche thingy they're into. They never needed to learn general basics that much, stuff just worked out of the box.
