We are in a bubble in the sense, less than 0.5 % of info created is consumed by actual people. And that stat is from 2015 -
https://www.un.org/sites/un2.un.org/files/attention_economy_... So you have to ask whats the point of the story?
Such stats become possible cuz advertisers who subsidize the whole mindless system, still make enough out of it.
So the question becomes - is there an upper bound to how much Advertisers globally can cough up?
As long as Global GDP keeps growing they probably can keep everything running. Post covid we are seeing what happens when Ad spends come down from a peak. Youtube/FB etc say drops in ad spend for the first time in their histories. Probably caused the layoffs in most of the freebie providing tech firms.
Second factor is how much Attention (that can be exploited) actually exists? Even if GDP keeps growing and ppl have disposable cash in hand, but ppls attention is so overloaded with info+spam then what happens? I haven't seen any great answers to that. But its obvious info overload is effecting people's ability to pay attention. Which effects the price of an ad.
Third factor is all the Spare Capacity built into the cloud to support actually paid services such Uber/Amazon/rest of corporate wonderland. Reddit, Twitter etc can handle such volumes purely because this excess capacity exists. Now if its diverted toward Crap-GPT et al and cloud prices rise for content mills things are going to get rough.
Fourth factor is the cost of handling private data security/privacy/spam/moderation/keeping ppl from exploiting each other seems to be growing. Currently the cost is showing up as govt fines and tomorrow in implementing random half baked govt regulations.
So you already have ppl selling books about the Subprime Attention crisis and predicting collapse. But even if the freebie/content providers/ad tech collapses the rest of tech - cloud - eCommerce - paid content/gaming etc is going to chug along just fine.
