NB, but your experience reflects mine. Though on a different system.
I remember discovering Usenet and how amazing it was. Not only isn't it what it once was, but what it once was leaves some things to be desired.
I remember discovering Slashdot and how amazing it was. ...
I remember discovering Wikipedia and how amazing it was. It's actually still pretty good, but the manipulators, idiots, and politics are brain-numbing and/or blood-chilling.
I remember discovering University and how amazing it was. It's actually still pretty good, but the manipulators, idiots, and politics are brain-chilling and/or blood-numbing.
I remember discovering books and experts and scientific articles and documentary series and ... Lots of stuff.
Some of it's still good. Some of it now strikes me as painfully stupid. Often it's not so much the answers that aren't known but the questions. Or we discover there are black swans and have to toss a bunch of priors. Or the words and moralities on which The Elders based everything on have changed beyond recognition. Or The Elders' message has been so distorted by a game of Telephone run a few millennia too long. Every generation or two, everyone seems to toss everything out (especially the good stuff I worked so hard on) and start making basic mistakes from scratch again.
That other system is called life. SO is a lot like life.
Understanding is hard, it doesn't transfer well, the Guardians of the Knowledge start seeing the primary goal as Guardianship rather than Knowldging.
Then something comes along and grinds everything into the dust and it's built up again and a new generation of bright-eyed, bushy-tailed young'uns comes along and discovers an invaluable resource.
So it goes.
