Interesting. In my experience, advertisement and the incentives around it have led to the most devastatingly widespread removal of value in human culture and social connections that we've seen in this generation. Huge amounts of effort wasted on harvesting attention, manipulating money away from people, isolating and fostering extremism, building a massive political divide. And centralizing wealth more and more.
The amount of human effort wasted on advertisement is staggering and shocking.
I don't think your average adult is inspired by the idea of AI generated advertisements. Probably a small bubble of people including timeshare salesmen. If advertisements were opt-in, I expect a single digit percentage of people would ever elect to see them. I don't understand how anybody can consider something like that a net good for the world.
How does non-consensually harassing people into spending money on things that don't need add value to all the world's citizens?
