Some valid points, but then they haven't offered any solutions and promoted the same platforms who use algorithms that are the cause of the problem by their own research.
Unless the solution was in the Ground News ad section, then they didn't. All they said in the "Something More Positive" was going back to the internet 20 years ago, which is not a solution...
There are plenty of solutions to improve the situation or change the direction, reversal is not possible. Neither from technological side nor societal side.
It's the Bilboa Bagging effect. It's yearning for a time that no longer exists. Both because you've grown and changed and the world has grown and changed. You'll never capture that again. And maybe it wasn't even the way you are remembering it in the first place.
At best you could attempt to replicate it with all of the new tech, people, and social norms but there isn't "reset the clock 20 years". Thats a lazy copout and hardly a solution. Why not just say "everyone just needs to be better"?
