Yeah, the biggest delineation is "world without computers and digital electronics" vs. the world after all that proliferated. I'd still consider the 80s and 90s part of the "modern" era, what we used to call the "information age" or "computer revolution".
Pretty much all our modern tech is just more advanced versions of the same shit we already had in the 80s. Even social media (BBSs).
Am a 41 year old dad who grew up with Quake, Doom, and Unreal Tournament, and now have a 12 year old son who is also growing up on games. The boomers who didn't have a clue are dying. Those were OUR parents who didn't know diddly squat about gaming, not this generation's parents.
Same as you don’t learn woodworking when ordering a table from Ikea, or learning medicine when going to a checkup.
Maybe I'm different than most, but I DO wonder how that table is made, and I do try to educate myself on how the medicines I take actually work. There's been times I've wasted almost an entire day binging Wikipedia.
I'm not saying I have in depth knowledge of fields outside my own, but I do make an attempt. Like, I'm not a gearhead at all, and I only care about cars being able to take me to work and back. But I do know how internal combustion works, and I have a general understanding of the components of an engine.
30 will be here a lot quicker than you think. I also used to think 30 was old AF when I was 20.
Now I'm 41 and I don't know how it happened so goddamn fast. Every year, I get more and more anxious about trying to get shit done before my time comes.
