- adverts seeks to hijack your attention away from whatever you were doing, which is a mental burden resulting diminished performance (in the case of a work environment), is downright dangerous in the case of traffic environments and lessens the enjoyment in the case of leisure activities.
- there is little to no ethical restriction on content; the advert that gets displayed is likely not that of the best product: it is the one whose owner paid the most money, and the ad that gets the most traction is the one that tells the best story, so perfused with lies by omission and other forms of deceit that we don't even notice any more.
- the ubiquity of ads causes an perpetual escalation of the struggle for attention, to the extent that we might credibly expect to get ads implanted in our brains eventually if we don't say enough is enough.
The solution seems simple enough to me: we need to establish a code of conduct for advertisers which at the core means that they may no longer shove ads down our throats at every junction; instead adverts should be freely displayed in separate spaces (like a dedicated page on each website) where people voluntarily could look for products and services that they need (or just to browse), much like the ad pages in newspapers of days now long gone by.
All we need is a mechanism that promotes this behavior, and sanctions breaches.
