Adtech has issues but the idea that traditional advertising which has zero feedback from users is gonna make a comeback seems silly. Paying marketers millions to launch campaigns in magazines or TV when you have no clue how it lands seems more fraudulent to me than Adtech where you can measure user impressions/clicks. This reads to me like a guy in a shrinking market lashing out at an existential threat.
These articles are all the same, complaining about adtech without any real understanding.
It's just tech, quite literally plumbing, that lets marketers put messages in front of people and see what happens next. The internet has made it more capable than ever but how it's used varies greatly and there are both great and terrible examples.
