I'll add something. The loss of trust -- knowledge and belief in true facts.
We no longer have any reason or justification for believing anything we find on the internet. It is so overloaded with junk that whatever true facts exist are buried below a mountain of misrepresentation and fabrication.
It's over. The beautiful network of sites to spread knowledge, to entertain, to express, to do business, to communicate with each other..... gone.
I'm lucky. At 73 I got to see it from before start to finish. Like the music of the 60's and 70's, it will never be that good again; the internet peaked and exploded and is destroyed for any real, useful purpose.
Control and surveillance are all that's left. Sic Transit.
Actually that's not quite true. There's Free Republic.
Thank God and Jim Robinson for that.
