I've been reading many articles about how web advertising may not be all that is promised. A recent Wired article talked about how much of advertising is being served to bots[0], a looming recession is going to make big companies significantly reduce their advertising budgets[1], and some companies like Uber have pulled out of web advertising at all without seeing much of a decline. This has led me to think about how much of the entire tech industry is based on the assumption that user data and hyperpersonalized advertising is worth a lot of money - should this assumption stop being true, what parts of the tech industry as we know it would survive?[0]https://www.wired.com/story/bots-online-advertising/
