Thank you. We need to stop thinking of growth as a reasonable metric for wellbeing or relevance of products. When a new product is introduced, certainly, looking how the market reacts is interesting. But many years down the line, things should stabilise. Does your (metaphorical) baker round the corner grow yoy? And yet, somehow their bread is still good, and they have no problem surviving, except when a company with far too much capital just bulldozes in, for example by selling under local market prices.
The solution to a problem is never to ignore it, lock it away, out of sight where it will just fester. The people who produce bullshit (maybe for a living, maybe as a hobby) don't just disappear.
Aggressive filtering of what people see in their feeds is not a solution. What do all those able to discern bullshit from factual content have in common? Exercise for the reader as I don't have a definitive answer. A proper education can be thrown away or ignored when convenient; some people just seem to have a good nose for bs. I dunno.
What civilization are you talking about? The US, western Europe, capitalism, formally educated people? Who is 'they'? There's enough people who just want to watch the world burn, and they're very much part of society, paying taxes and going to clubs and shopping malls. For instance, all those highly capable developers and mathematicians on adtech payrolls. How is one supposed to concentrate on separating the wheat from the chaff when things engineered to distract and capture attention do exactly that?
You should check out what happened less than a century ago. Among other things, it started this whole digital conundrum.
It's naive to think that concentrating so much power over so many people in the hands of so few people can go any sort of well. What happens when the regulators, or the ones charged of overseeing them, want in on the fun? What if they're coerced, which suddenly is trivial to do?
Progress comes from individuals, as such, individuals should be empowered by great tools to make the most of their data. Wanting corporations to solve all the problems is another case of pushing off personal responsibility.
I recently read Biodiversos by Stefano Mancuso and Carlo Petrini, the founder of the slow food movement. It's basically a discussion between the two where they lay out the big problems with our production and consumption of food.
For instance, concentrating on making single kinds as productive as possible instead of cultivating variety is extremely dangerous, as shown by this event. The great Irish famine is maybe the most striking example. Humanity does exactly that with wheat, cows, almost everything. The very basis of most of the globe's food comes from a handful of species. In my mind, this is one of the great ticking bombs of our close future.
