I missed the very early years of computing, but for me the heyday was the Flash years. I got a copy of Flash and I felt like I could do anything—all the cool games were built by the same tool that I had installed on my computer, and my budding programming skills were like black magic to my friends and family. It was a superpower. Meanwhile, the internet in those days was small and populated mostly by smart and interesting people gathered in small-to-medium sized phpBB servers. The rise of Facebook and smartphones spelled the end of that era, and everything since then has been shallow and hollow by comparison as the internet began catering for the lowest common denominator.
That said, now I'm stuck reevaluating my perspective on all that. For this author, my own golden age was after the fall of theirs. I was part of the wave of users who had it too easy—the upstarts who intruded on the good thing they had going.
There are two broad explanations I can think of for this:
1. Computing has been declining since the 90s and my golden age was genuinely less good than the author's.
2. Each generation gets cranky and nostalgic with age, and this is just another case of "back in my day".
The modern internet feels so genuinely terrible that I can't help but think it must be #1, but #2 is such a common cognitive bias that I can't really dismiss it either.
