I agree with the author, but I also don't see lower usage of all this already meaningless human-produced content as inherently bad.
The hope is dim, but I do wish being online would be restricted to strictly work-related purposes and we'd be forced back to human-to-human interactions as primary modus operandi. We'd see the depression and polarization rates go down significantly. These online community feedback loops are too toxic and bring little to the table.
If nothing online can be trusted then only offline can be the way to go, up until you people (the ones screaming Luddites at everyone 'normal' here) will decide that we need start augmenting our bodies to make better future, or in other words make profit to line your pockets.
I work in ML btw (for a loooong time).
